This chapter caught my eye because I learned some things that I thought I knew but it turns out I was wrong all along. For example I thought that car companies used dummies to test the protection the car exerts when impacted like the ones they use in commercials. But I was wrong a dummy is used to tell you how much force a crash is unleashing on various dummy body parts. Cadavers then come in and help figure out how much force human body parts can take in side impacts, front impacts, and rear impacts. I also believed that you could get a concussion from hitting your head really hard on a hard surface like the side walk. You really get one from banging your head into something and whipping your head in one direction and back really fast. The biology concepts that were addressed were basically research being done with human and some animal cadaveric specimens testing the safety issues. I think that we will do some research on animal cadaveric specimens in this biology course although they might not be about safety we will most defiantly learn something while doing it.
I was also very surprised to find crash test dummies were not used to test the protection of the car's airbags, and that cadavers were used in these processes. I think it is amazing what we can do now with dummies or cadavers to prevent more serious injuries or death in minor car accidents.
I agree with what you wrote, this chapter exposed the reality of how car companies actually use cadavers to test how much force a human body part can take before it breaks from different angles of a car. What’s even more surprising is the fact that the car companies use dummies but only to find out how much force a crash makes.
I was also surprised that cadavers were used to test how much force a body part can take before breaking. I did not know that you could get a concussion just by hitting your head and whipping your head back and forth fast, but it is hard to get a concussion by just hitting your head.
I was just as surprised as you when I learned that actual human cadavers were being used instead of the crash test dummies that we see all over car commercials on TV. We also had many of the same thoughts while reading through this chapter.
I find my reaction to this chapter is similar to yours, as I also never knew cadavers were used in crash tests. In fact, I never even knew what a cadaver was until I read "Stiff". I will say it is very obvious why car companies would show the use of dummies in commercials instead of cadavers for, well, obvious reasons (cadavers don't make too many appearances on television anyway).
I was as surprised as you to be honest, I never came to think that actual cadavers were used instead of test dummies for a crash simulator. I think that's great because we can prevent lots of injuries or death in car crashes.
I comply with what she wrote that i also thought car companies use test dummies too. It was really stuning to know that they use actual cadavers to test cars.
Just as you, I was shocked when I read that they used actual cadavers to utilize as test dummies in a car. I think it's a good way that enables them to use test crashes and the impact it causes on a human body. However, it is a little disturbing.
I also thought the same thing, I never imagined that they used actual human bodies to test the amount of force a human body can take. I always thought they used dummies but I guess I was also wrong.
This chapter was very interesting to me. It opened my eyes to things that I thought I already knew but i was so wrong about. Like I had no clue that car companies used cadavers to help figure out how much force human body parts can take in impacts.
I also agree that this chapter was very interesting. I was amazed that they used cadavers to test the impact of car crashes and because of that we have safer and more advanced cars.
I was not surprised to find out that a Cadaver was used to test airbags, they still are extremely dangerous and I believe they should use crash dummies. At least they could scale the impact force so that they can be made a tad bit safer because personally it's been said that you could be injured by an airbag worse than in a small car crash. Of course, it saves you from whacking your head on any object in the car, but instead cracking your ribs? I'd much rather be knocked unconscious. I understand that the companies are only trying to keep us safe but I seriously believe that it should be tested more.
I also agree the chapter had caught my attention because of instead of test-dummies being used to test out cars there were cadavers. But because of these cadavers today we drive in more safer cars.
what surprised me even more was that people actual took a part in these tests. i would have never thought that anyone would agree to do that. that is mostly one of the reasons i found this chapter particularly interesting.
I too agree with you on how this chapter was an eye opener. I never knew that car companies use cadavers, which is very intelligent. This chapter appealed to me not only because of my interest in cars but also because of the use of humor, like in the other chapters.
I do agree that this chapter is astonishing because i didn't know that car companies not only use dummies but also cadavers. Also that the cadavers don't drive the cars they get hit wit a powered piston with a specific amount of force
I agree with Ahnyia's post due to everything I learned as well, I never knew that cadavers were used in crash tests until I read this chapter. I also didn't know that a concussion could be caused so easily by whipping one's head furiously.
i agree with you i believe that the use of cadavers was a real improvement because it has the structure of the human but not only that it had the same weight and same insulation due to the muscle mass as a normal human
I agree with both of you. I found it very interesting to learn that a human cadaver is used in the study of a car crash test. I think it was very smart of someone to have come up with crash tests being tested on cadavers rather than test dummies.
i was extremely surprised when i read this chapter because like all these comments i was also not aware at all that cadavers would be used to test the amount of impact someone can take.
This chapter of Stiff was about the use of cadavers to improve car safety. I think its pretty cool how they use cadavers to see the effects of a crash from many possible angles. They use that data to improve their seat belts, air bags, etc. Its a lot more productive than simulations or crash test dummies because cadavers give you what simulations can't: real bones, real skin, and real organs. It is much more accurate to test impact with actual human bodies. This will come up in Biology because the use of cadavers are not only used in testing cars.
The use of cadavers in crash tests is very helpful indeed in terms of determining how to improve driver safety during collisions. I agree with you that they are certainly much more useful in getting results than crash test dummies, due to the fact they accurately reflect the impact of unique crashes on the human body.
I also agree with the writer in that you can't test for broken bones or concussions with a plastic crash test dummy. And it is also important for car manufacturers to continually improve safety in cars.
I agree with you, I think cadavers being used for crash test can definitely improve car safety. Without the cadavers who knows how much force a human body can take from a crash, I found this pretty interesting and helpful for many people who are involved in crashes.
Yes, i agree that it is cool some perspective on the truth of crash tests. I think it's important but a bit humorous to see dummy's or cadavers get thrown at high speeds while they just fall over like nothing happened.
I liked this chapter because it is about cadavers being used in car safety and the picture of that flying Cadillac at the book is awesome. This chapter interested me because I did not know that cadavers were used in crash tests. I think this relates to Biology because it shows how a dead body is used in a scientific test and how it reacts to the impact and also its reactions at an actual body not at crash test dummy that can only measure the G force of the collision. I think it is better to use cadavers instead of crash dummies because they give a much more accurate result at the actual damage at the human body in car collision than a crash dummy does. Also I think this is going to help when we do an actual test with a dead body at our Biology class.
This chapter was really interesting and I had never known that cadavers were used to determine a car's safety. I believe that it's really beneficial to use bodies in crash tests because you can accurately measure the amount of damage taken on the human body and can asses what measures need to be taken to prevent these injuries during car crashes.
This chapter informed me about scientists using cadavers instead of dummy to measure the amount of damage. It's way much better. And I do agree with what you said about this chapter being related to biology.
This chapter was very interesting for me. I had never known that cadavers were used to test car impacts; I always thought that crash dummies were used, but apparently cadavers are used to see how much force a real body part may take, and how it will fare in an accident. This relates to biology because testing was done upon Cadavers, and how their various body parts hold up to various forces and I believe that we will learn about human body parts and how they break or crush.
I agree that also interested me but it would make sense that they use a cadaver being that its the human bone structure but also at the same time you would believe it wouldn't be completely accurate due to the bone getting brittle after a while
I agree with you. I always thought that crush dummies were used to test things on cars but apparently there's more to it. I didn't know that cadavers would've been useful to this area until now.
I found this chapter to be interesting in the fact that it introduced to me the thought of human cadavers as a crash test dummy and it made me recognize that it was a good idea due to a cadaver having the same bone structure, same muscle mass, same arteries and organs as a human and it was a lot safer due to not having to put a person in harms way and i believe this is related to biology because it dealt with organs and bones having to undergo various straining processes
I also found it just as interesting, but I was a bit bothered by this chapter. I honestly wouldn't want my body to be used as a crash test dummy...and it even would feel uncomfortable taking part of a crash test with cadaver. I don't why. It just feels too creepy.
I also found this chapter to be very interesting as I learned about the crash test dummies. I agree with what Celine said as well. I definitely wouldn't feel comfortable to even take part of a crash test using a dead human body.
I agree with your interest in how crash dummies are actually humans, in a way it's taboo how the way we keep safe is to use actual people to take the impact for us and then study what happened to them.
I found this chapter interesting because they use the dead as test dummies in cars instead of using actual dummies. The reason they do that is because a real person shows what would happen in an accident. Without a cadaver dummies are useless because we wouldn’t know how much force they can take. The biology concept that is addressed in this chapter is that the combination of rotating the head and then going in the other direction can cause serious brain damage. This can tie into our biology course because we might be learning about the brain and the effects of car accidents. My personal interpretation of this chapter was that I learned a lot of information on the dead and cars.Always wear your seat belt or else you you could have serious brain damage if you're in an accident.
I agree with what you say about this chapter. It was compelling to know that using cadavers are more appropriate to test crash impacts and find useful information than what test dummies give you. Possible Biology concepts that may be used is studying the brain, and the amount of force a human body can withstand. The only thing I disagree with is wearing your seat belt. It can harm your body from rupturing things that can be fatal. At the same time, it will not save you from side impacts, so wearing a seat belt may not be the best option.
This chapter was one of the more interesting chapters for me. I wasn't really 100% sure if they did use human cadavers for crash tests, but now I know. I think that using actual human bodies for crash testing can make results much more accurate to what could happen to a living human. Dummies are also effective but I dont think that they would ever be able to match the real thing. In this chapter I was able to learn many things including all the different ways that researchers test to ensure a car would be safe enough for a living person to drive and I learned that brain damage was one of the major culprits of being in a car crash, I would have thought it to be broken bones or spinal injuries.
I would have to agree and disagree with you. I would agree with you because I do see that if real humans were used we would get a much more accurate result from using a living human being. But I would have to disagree with you because I think using a real human would be bad, chances are they can even die because we don't necessarily know how much force a living human can sustain. In this case it would be more beneficial to use a cadaver where they cant feel pain and there can be something to show how much pain a real human can sustain.
I agree with both of you in a way. Alex you're right about how we dont know the amount of trauma a human can sutain in a car crash but logically this is as close as we can get without putting someones life in danger, so we use these dummies as our best estimates.
I found chapter 4 of "Stiff" to be a bit underwhelming in terms of attention-grabbing as it seemed to be more focused on the studies and repercussions of using cadavers as crash dummies and the author's telling of her experience at a cadaver research site.
An anatomy concept covered in this lesson is how durable parts of the human body are to traumatic impact or force.
This chapter focuses on the use of cadavers as crash test dummies in order for car manufacturers to determine different safety measures. Significant parts of the chapter include a bit of history of cadaver research (which in itself includes a case of attempted political intervention) and the author's experience of being at an actual cadaver research site.
I don't completely agree with you since I found this chapter very interesting and I was able to learn something new, but I do agree with you on the description of the chapter and its significant parts.
I completely agree with you, this chapter is very luring. It actually one of my favorite chapter. Before I didn't agree with cadaver testing. Now I'm 100 % for it. I feel, that because of cadaver being tested cars are now more safer than they were lets say in the 19 century.
I found this chapter interesting because i believed they only used test dummies for a crash simulator. I never came to think they used actual dead bodies for that. At the same time I think that's great because with a real body we can actually analyze what happens in reality. Real skin, organs, bones, etc. To me it became apparent that the biology concept in this chapter would be testing the human body.
It's funny how some facts can surprise you. When you think of donating bodies for science you believe that its just using organs or studying in a lab on a table but these are cadavers in action. I definitely understand your point of view. And all we want in science is accuracy so thats probably why we use the caddavers as dummies like you mentioned.
I can totally relate to my reaction with you Ashley, I feel because cadavers are being used as dummies, car manufacturers are able to determine different safety measures and improve the vehicle it self. It true too what you say Paula like when one donates their body to science you only think that it'll be used for organ transplants etc. But now that I know its going to be used for experiments to better improve vehicle safety I feel like I would feel be more comfortable donating my body to science than letting it go to waste.
This chapter surprised me because I learned that cadavers are used as crash dummies other than just dummies. I just thought that car companies use plastic human like dummies to test the protection the car exerts when it crashes so the human being would mostly not die but have a few injuries because of all the commercials I have watched in the past. But I was wrong. Mary Roach wrote, "A dummy could tell you how much force a crash is unleashing on various dummy body parts, but without knowing how much of a blow a real body part can take, the information is useless." Cadavers are used to test the impact from the front, rear, and back of these test cars being made. The concept would have probable been the force of damage taken on the cadavers and how the cadaver's dead body would have taken the impact externally and internally. This chapter explains the use of cadavers as crash test dummies in order for car companies to determine safety measures and damage impact of how a real living human would take.
I was under the same impression as you about car companies solely using dummies for crash tests. It makes much more sense to use cadavers as it gives car manufacturers important information about how to make vehicles keep drivers safe in certain types of collisions.
I was also amazed when I read that cadavers were used as crash dummies. I, now, fully understand their significance in the tests. They are much more useful than I thought.
This was probably one of the most surprising chapters of them all, because I would have never thought that cadavers would be used to test out car crashes. Obviously now I realize using test dummies would not give you the details needed to create a safe vehicle in the chance of an accident. Biology plays an important role in crash tests, as vital organs and other body parts need to be protected in order to prevent death or fatal injuries. I personally found myself going, "Ooohh!" after realizing what Mary Roach meant after naming the title "Dead Man Driving". I thought it could have meant testing out sudden heart failures or something, so I felt kind of silly after finding out what it truly meant. I felt even more silly when I realized the text on the first page wrote, "Human crash test dummies and the ghastly, necessary science of impact tolerance". That's when I realized that I skipped some pages after picking the book back up from where I left off.
Ha, I do gotta say this chapter puts the book into play in what a human body reacts to and can be used to find out about every day situations. But the sentence you wrote "Human crash test dummies and the ghastly, necessary science of impact tolerance", definably makes perfect sense, if you sum up the whole chapter into one sentence this would probably be it.
I was interested in this chapter at first because of the name "Dead Man Driving", but I figured out that they actually used cadaver crash test dummies. I always thought that the only crash test dummies were the real dummies (plastic and metal ones) to test G loads. If you are testing for broken bones and concussions than a cadaver is a much better choice since a crash test dummy doesn't have a brain. I found it interesting how hard of a time the workers were having putting the cadaver in the car. It ties into biology because when they did the tests the were seeing how far the human body would go in a car crash without injury or death.
Yes, I also believed that in test crashes, only test dummies were used, and it was in fact intriguing that the most difficulty the team had with the cadaver was such a small thing as positioning it.
I do got to say this chapter might have a silly title, but makes you want to read on, but unlike then, we use fake life sized crash dummies with computers to measure the amount of G loads a crash forces upon the dummy, but tho one thing about this is, you can't measure if someone was to brake a leg like what you said, so i would believe cadavers might be a better test dummy to test the possibility for broken bones and so on.
To start off this chapter has an attention grabber title. I never knew that they used Cadavers to test crashes. So that fascinated me the most in this chapter. In this chapter it explains the impacts on your brain when in a collision. Cadavers are a great replacement next to real practice dummies. Although practice dummies are good to test on to. It does not necessarily show the damage the body will undergo. It relates to biology to by showing the ways it can effect the brain.
I agree that this really is a fascinating chapter especially as they describe just exactly what happens to the cadaver during impact. Also, it's true that the best way to test vehicles is with cadavers which is the closest they can get to a live human
This chapter is also one of the most interesting chapters in my opinion. The reason why is because I would have never thought that cadavers would be used as crash dummies. Also, I enjoyed the fact that with the cadavers being used for the test that we could figure how much force a cadaver can hold. A biology concept is that we can simply figure how much force and pressure a human cadaver can sustain in order for a human to live from a motor crash. My personal interpretation of the text is that it mainly focuses on Mary Roach heading to a crash test place, where cadavers are crash test dummies and they are used to find out how much force from a crash a human can sustain in order to make vehicles a lot more safer in the future.
I too believe that it is shocking to use cadavers as crash dummies, it just seemed a really far fetched idea; however, it's great that they are being used for the benefit of the public.
This chapter mainly captured my attention because it discuses the usage of cadavers to test automobile crashes. Although I knew that for cars to be the way they are now many tests must have been executed to ensure their safety, I just never made the connection nor imagined that cadavers were involved, instead I always believed that test dummies were used for these experiments. However, it makes perfect sense since using dummies or animals would not yield as accurate results as cadavers would. It's incredible all the experiments that have to be done on the cadavers to try to find the injury threshold by testing the limits of human resistance and the damage caused by such impacts. Also, the autopsies that must be preformed to determine the internal damage to the tissues, blood vessels, and internal organs as well as bones. Probably the most impressive part of the chapter though, was hearing about the scientists that were so passionate about their research that they risked their lives undergoing various crashes in hopes of also finding the injury threshold, and making automobiles safer for the public.
The chapter, Dead Man Driving, was an informative chapter. The chapter comprised of information regarding driving safety. Roach was able to see cadavers being used as car crash dummies. The cadavers allowed the scientists to discover the amount of impact the human body can take, mainly the shoulder, coming from the side. The cadavers were immensely important when being tested for cars. They allow for progression in car safety. It will prevent more deaths and serious injuries while in a car. Cars will also become more efficient and safer for a person to drive. For most of my life I thought that car company's tested there cars using fake dummies. After reading this chapter, I understood why actual bodies were used. It allows for maximum results.
Cadavers as crash dummies was pretty funny to me seeing how in commercials we always see like stuffed dummies and not people. I do though agree that it does prevent more injuries in car accidents because we are able to prevent that with the test crashes.
In this chapter I was very surprised in the title “ dead man driving”. Honestly, I did not know what to expect in this chapter. This chapter describes how cadavers are used with car crash studies. I never would have known that cadavers were involved in the studies on crash test. I was amazed in how cadavers (such as um006) are used to figure out how much force a human can handle without serious injuries. All of this information studied is then used for other parts and details of a car to be made or improved. I believe it is intelligent for studies to happen on cadavers rather than dummies for the reason being more accurate results. I also learned that at specific times, animals were also used to test other impacts in car crashes. Like many chapters in this boo, I learned many new things I probably never would have learned without reading this book.
This chapter was mainly focused on safety in driving and how cadavers were used as crash dummies. This really proves the cadavers endless use to not only living but to help bebing safety to the living. I always believed that crash dummies were completely artificial but I guess that the best way to find out about safety is by using people to test it. The bumps and bruises examined to predict the damage that would be done to a consumer would relate to a topic that we will cover in this class. This chapter hit personally with me since I was in a very bad car accidents so I can imagine how it would feel to put an actual person to test the crashes.
I found this chapter very interesting because it didn't have to do with cadavers being used by physicians but by car companies. I also did not know cadavers were used as est dummy's, it makes sense to use them because they're actual human bodies. The anatomy concept in this chapter has to do with the durability of the human body; the bones especially. My interpretation of this chapter was that it was about how cadavers are applied to car safety. If it weren't for cadavers being used as test dummies for cars most people would die in car accidents.
This chapter in stiff was really about car companies used cadavers to test out cars. Which was something I didn't know, I thought test-dummies were plastic bodies not actually cadavers.My interpretation of this chapter is how cadavers contributed to making a more safe driving environment. These studies allowed car companies to make safer cars for use to drive today.These chapter relates to anatomy and how much damage a human body can take.
This chapter went over how cadavers and dummy's are used to test the various outcomes of car accidents and implement the data to ensure safety in vehicles via airbags or seat belts. What I found the most interesting however is how vehicle history progressed over time. The author explained that before there were no windshields, to lethal and dangerous windshields, to safe windshields. I also found it interesting how the steering wheels of old cars would crush the body and damage vital organs. Also, the stand of the steering wheel would directly impale the heart which lead to collapsible stands. In this chapter, it is clear that vehicle safety has come a long way and it was because of various dummy's and some cadavers that made that sacrifice.
It is nice to see how far vehicle safety has improved over time. I wasn't aware that some would have no windshields and that steering wheels were at such high risk of killing someone if they got involved in an accident. Cadavers have really contributed to vehicle safety over time and I think they should deserve more credit among others.
Ha ha, "cadavers that made that sacrifice." The impact cadavers have had on car safety is evident through the changes implemented in car manufacturing. I mean, we went from the 1970 Datson 240Z to the 2014 Nissan 370Z thanks to these dead meats!
this chapter had to be one of my favorites because as much as i am not interested in cars all the reading about how they came to make cars so safe made me want to know so much more about cars and how they come to be built. also another thing that was very interesting was the think about swinging your head can give you a bad concussion that was very surprising to me and i really made me think more about how serious and fragile your body is. In this chapter there were some little footnotes that also came to my attention talking about how back in the days cars were bought because of the way they looked so people didn't care that they would save their lives.
I agree, it's sad that back in the day people cared more about the look of the car rather than the safety it would offer. The Survival Car would've saved a lot of lives that were lost in fatal accidents which is rather unfortunate. It is interesting how swinging you head at a fast motion, like in a car crash, could put you in a coma. It does remind you that although the human body could withstand a lot, it can also be damaged easily.
I had no idea that cadavers and cars would be related. The cadavers were used to help determine the safety of cars. There was also a lot of information about certain fatalities that can occur in a car crash. It makes sense to use the actual dead bodies. I think its amazing and unbelievable that some people actually volunteered to be used as dummies. I felt really bad when I heard read that animals were used in automotive impact testing. Pigs are very similar to humans. Since they have a similar organ setup as human beings, they were used more regularly.
I was shocked as well when I read there were volunteers for these tests. They must have been incredibly passionate about their research and they may have cared for people to be safe. They are kind of like heroes in a way in my opinion.
Learning that there were indeed volunteers for such car tests had me in shock as well. It takes conviction to risk one's own life in order to progress in car safety. Sad, because I don't think stunt men are as cool anymore.
In the fourth chapter of Stiff, I was shocked to learn that cadavers would come of use for car crashes. Usually, commercials show dummies crashing into walls at fast speed to show its safety advantages so I assumed that dummies would be used for that type of research. Then again, it would be unsettling seeing a corpse on television on a car commercial. The biological concepts found in the chapter had to do with certain injuries that could be presented in car crash and how the cadavers help a lot with preventing another fatal car crash by using them as their test subject. I found that the idea of using pigs for the research was really smart with them having organ setup similar to humans. Overall, I enjoyed the chapter.
Who could have known that cadavers were used in automobile companies to see what type of car crash damage could be done to a human being. Dummies are use to see how mush force is put on a dummies body part when it crashes. The first windows use in cars were glass window which were easily broken into by the drivers head giving him gruesome cuts. Then came tempered glass which was strong enough to keep the head from going through the class but it could cause serious brain damage. Brain damage is the major culprit ( as Mary Roach says) in car accidents. Its the brain going in one direction then going rapidly back that cause brain damage. Then came in the type of steering wheel that would hit the chest of a person and kill them when they hit it with enough force. Of course this was before the seat belt was invented. Also the type of seat belt could have killed you in a car crash.
This chapter I found to be very interesting because the logic it held, behind the reasoning of using cadavers as crash test dummies. I was like many who thought dummies was used in in car crash test. But I'll prefer to use cadavers, because it will give crush test more accuracy. Because the damage the cadavers will receive can simulate what a living person can wittiness in a car crash. So I believe its better to test a car with someone already dead instead of recalling a car that had a low crash-accident rate.
This chapter of the book was really informative because i never knew that cadavers where use for crash test i knew they used crash test dummies but i never knew that they use crash cadavers, I think that a cadaver gives a much better understanding of the forces the human body is experiencing when a car crashes head on to a wall.
I always thought that dummies were used for crash tests to see the damage the car would give to the person, I never knew that cadavers would be used. On top of that, I also didn't know that the cadavers would be used with such high tech equipment, and it would be used to see the exact force a car would give to a passenger/driver. I think this is a very important and effective practice.
I loved this chapter because it talks about cadaver being used as test dummies .I never knew that they did that sort thing with cadavers honestly. I was so interested after reading the title of this chapter but i was kind of disappointed with what i read. I was expecting something way more exciting.
Chapter four mostly talks about how cadavers are being tested on the impacts on test crash impacts and the effect that it has on their body. Roach states that cadaver testing is one of the most accurate testing since they are a human being as well as the fact that they have the ability to feel no pain. Also, because of cadaver testing on car accidents, it has improved safety measurements when creating a car, decreasing the number of car accidents that happen.
Who would’ve thought? Cadavers and cars… think you know a (dead) guy. I was deflected with awe after having read, “Over the past sixty years, the dead have helped the living work out human tolerance limits for skull slammings and chest skewerings, knee crammings and gut mashings: all the ugly, violent things that happen to a human being in a car crash” (Roach 87). I now realize that the process was vital for the progression of car safety. Without advancements in car safety... It wouldn’t be safe. All in all, I felt like a dummy while reading this chapter. Ha. Ha.
The chapter got my attention because I have always heard that they had car-testing dummies to test all of the safety issues before the car is manufactured to the masses. As I started reading the chapter, I realized that I was completely wrong. Cadavers are actually used to test how much force human body parts can take in impacts from all sides. The chapter also explains how you can get a concussion from hitting your head on something or whipping it back and forth really fast. This relates to biology because it is testing the safety of car impacts with human and animal cadavers.
Reading this chapter I learned that cadavers weren't just used for analysis and research in a science lab but for another thing that I would've never thought about! They are used as dummies to test out car impacts! They are more specifically used to examine how strong human body parts are against impacts. I found this so interesting because it was honestly something that I previously had a knowledge about.
This chapter caught my eye because I learned some things that I thought I knew but it turns out I was wrong all along. For example I thought that car companies used dummies to test the protection the car exerts when impacted like the ones they use in commercials. But I was wrong a dummy is used to tell you how much force a crash is unleashing on various dummy body parts. Cadavers then come in and help figure out how much force human body parts can take in side impacts, front impacts, and rear impacts. I also believed that you could get a concussion from hitting your head really hard on a hard surface like the side walk. You really get one from banging your head into something and whipping your head in one direction and back really fast. The biology concepts that were addressed were basically research being done with human and some animal cadaveric specimens testing the safety issues. I think that we will do some research on animal cadaveric specimens in this biology course although they might not be about safety we will most defiantly learn something while doing it.
ReplyDeleteI agree with you that this chapter was a real eye opener. Especially on the issue of using cadaver not crash test dummies for certain tests.
DeleteI was also very surprised to find crash test dummies were not used to test the protection of the car's airbags, and that cadavers were used in these processes. I think it is amazing what we can do now with dummies or cadavers to prevent more serious injuries or death in minor car accidents.
DeleteI agree with what you wrote, this chapter exposed the reality of how car companies actually use cadavers to test how much force a human body part can take before it breaks from different angles of a car. What’s even more surprising is the fact that the car companies use dummies but only to find out how much force a crash makes.
DeleteI also was just surprised as you that scientists used cadavers to do crash tests because they give a better result than a crash dummy does.
DeleteI was also surprised that cadavers were used to test how much force a body part can take before breaking. I did not know that you could get a concussion just by hitting your head and whipping your head back and forth fast, but it is hard to get a concussion by just hitting your head.
DeleteI was just as surprised as you when I learned that actual human cadavers were being used instead of the crash test dummies that we see all over car commercials on TV. We also had many of the same thoughts while reading through this chapter.
DeleteI find my reaction to this chapter is similar to yours, as I also never knew cadavers were used in crash tests. In fact, I never even knew what a cadaver was until I read "Stiff". I will say it is very obvious why car companies would show the use of dummies in commercials instead of cadavers for, well, obvious reasons (cadavers don't make too many appearances on television anyway).
DeleteI was as surprised as you to be honest, I never came to think that actual cadavers were used instead of test dummies for a crash simulator. I think that's great because we can prevent lots of injuries or death in car crashes.
DeleteI comply with what she wrote that i also thought car companies use test dummies too. It was really stuning to know that they use actual cadavers to test cars.
DeleteJust as you, I was shocked when I read that they used actual cadavers to utilize as test dummies in a car. I think it's a good way that enables them to use test crashes and the impact it causes on a human body. However, it is a little disturbing.
DeleteI also thought the same thing, I never imagined that they used actual human bodies to test the amount of force a human body can take. I always thought they used dummies but I guess I was also wrong.
DeleteThis chapter was very interesting to me. It opened my eyes to things that I thought I already knew but i was so wrong about. Like I had no clue that car companies used cadavers to help figure out how much force human body parts can take in impacts.
DeleteI also agree that this chapter was very interesting. I was amazed that they used cadavers to test the impact of car crashes and because of that we have safer and more advanced cars.
DeleteI was not surprised to find out that a Cadaver was used to test airbags, they still are extremely dangerous and I believe they should use crash dummies. At least they could scale the impact force so that they can be made a tad bit safer because personally it's been said that you could be injured by an airbag worse than in a small car crash. Of course, it saves you from whacking your head on any object in the car, but instead cracking your ribs? I'd much rather be knocked unconscious. I understand that the companies are only trying to keep us safe but I seriously believe that it should be tested more.
DeleteI also agree the chapter had caught my attention because of instead of test-dummies being used to test out cars there were cadavers. But because of these cadavers today we drive in more safer cars.
Deletewhat surprised me even more was that people actual took a part in these tests. i would have never thought that anyone would agree to do that. that is mostly one of the reasons i found this chapter particularly interesting.
DeleteI too agree with you on how this chapter was an eye opener. I never knew that car companies use cadavers, which is very intelligent. This chapter appealed to me not only because of my interest in cars but also because of the use of humor, like in the other chapters.
DeleteI do agree that this chapter is astonishing because i didn't know that car companies not only use dummies but also cadavers. Also that the cadavers don't drive the cars they get hit wit a powered piston with a specific amount of force
DeleteIt was fascinating to read about the ways cadavers were used by car companies. I never knew that companies actually used cadavers for safety testing.
DeleteI agree with Ahnyia's post due to everything I learned as well, I never knew that cadavers were used in crash tests until I read this chapter. I also didn't know that a concussion could be caused so easily by whipping one's head furiously.
ReplyDeletei agree with you i believe that the use of cadavers was a real improvement because it has the structure of the human but not only that it had the same weight and same insulation due to the muscle mass as a normal human
DeleteI agree with both of you. I found it very interesting to learn that a human cadaver is used in the study of a car crash test. I think it was very smart of someone to have come up with crash tests being tested on cadavers rather than test dummies.
Deletei was extremely surprised when i read this chapter because like all these comments i was also not aware at all that cadavers would be used to test the amount of impact someone can take.
DeleteThis chapter of Stiff was about the use of cadavers to improve car safety. I think its pretty cool how they use cadavers to see the effects of a crash from many possible angles. They use that data to improve their seat belts, air bags, etc. Its a lot more productive than simulations or crash test dummies because cadavers give you what simulations can't: real bones, real skin, and real organs. It is much more accurate to test impact with actual human bodies. This will come up in Biology because the use of cadavers are not only used in testing cars.
ReplyDeleteI agree with the author that it was pretty cool to see the effects of a crash in really vivid wording.The writer of this post did a really good job.
DeleteThe use of cadavers in crash tests is very helpful indeed in terms of determining how to improve driver safety during collisions. I agree with you that they are certainly much more useful in getting results than crash test dummies, due to the fact they accurately reflect the impact of unique crashes on the human body.
DeleteI also agree with the writer in that you can't test for broken bones or concussions with a plastic crash test dummy. And it is also important for car manufacturers to continually improve safety in cars.
DeleteI agree with you, I think cadavers being used for crash test can definitely improve car safety. Without the cadavers who knows how much force a human body can take from a crash, I found this pretty interesting and helpful for many people who are involved in crashes.
DeleteYes, i agree that it is cool some perspective on the truth of crash tests. I think it's important but a bit humorous to see dummy's or cadavers get thrown at high speeds while they just fall over like nothing happened.
DeleteI liked this chapter because it is about cadavers being used in car safety and the picture of that flying Cadillac at the book is awesome. This chapter interested me because I did not know that cadavers were used in crash tests. I think this relates to Biology because it shows how a dead body is used in a scientific test and how it reacts to the impact and also its reactions at an actual body not at crash test dummy that can only measure the G force of the collision. I think it is better to use cadavers instead of crash dummies because they give a much more accurate result at the actual damage at the human body in car collision than a crash dummy does. Also I think this is going to help when we do an actual test with a dead body at our Biology class.
ReplyDeleteI also agree that it is better to use cadavers as test dummies because it can accurately predict what can happen in a car accident to a living person.
DeleteThis chapter was really interesting and I had never known that cadavers were used to determine a car's safety. I believe that it's really beneficial to use bodies in crash tests because you can accurately measure the amount of damage taken on the human body and can asses what measures need to be taken to prevent these injuries during car crashes.
DeleteI enjoyed this chapter due to that reason, you could get a much better measure of damage like Melida said than using a crash dummy.
DeleteThis chapter informed me about scientists using cadavers instead of dummy to measure the amount of damage. It's way much better. And I do agree with what you said about this chapter being related to biology.
DeleteThis chapter was very interesting for me. I had never known that cadavers were used to test car impacts; I always thought that crash dummies were used, but apparently cadavers are used to see how much force a real body part may take, and how it will fare in an accident. This relates to biology because testing was done upon Cadavers, and how their various body parts hold up to various forces and I believe that we will learn about human body parts and how they break or crush.
ReplyDeleteI agree that also interested me but it would make sense that they use a cadaver being that its the human bone structure but also at the same time you would believe it wouldn't be completely accurate due to the bone getting brittle after a while
DeleteI agree as well! I was also very shocked that you can get a concussion just by whipping your head back and forth really fast.
DeleteI agree with all of you. To Ashley, it surprised me as well. I thought 'Oh, you move your head back and forth, so what you?' I was rudely mistaken.
DeleteI agree with you. I always thought that crush dummies were used to test things on cars but apparently there's more to it. I didn't know that cadavers would've been useful to this area until now.
DeleteI found this chapter to be interesting in the fact that it introduced to me the thought of human cadavers as a crash test dummy and it made me recognize that it was a good idea due to a cadaver having the same bone structure, same muscle mass, same arteries and organs as a human and it was a lot safer due to not having to put a person in harms way and i believe this is related to biology because it dealt with organs and bones having to undergo various straining processes
ReplyDeleteI also found it just as interesting, but I was a bit bothered by this chapter. I honestly wouldn't want my body to be used as a crash test dummy...and it even would feel uncomfortable taking part of a crash test with cadaver. I don't why. It just feels too creepy.
DeleteI also found this chapter to be very interesting as I learned about the crash test dummies. I agree with what Celine said as well. I definitely wouldn't feel comfortable to even take part of a crash test using a dead human body.
DeleteI agree with your interest in how crash dummies are actually humans, in a way it's taboo how the way we keep safe is to use actual people to take the impact for us and then study what happened to them.
DeleteI found this chapter interesting because they use the dead as test dummies in cars instead of using actual dummies. The reason they do that is because a real person shows what would happen in an accident. Without a cadaver dummies are useless because we wouldn’t know how much force they can take.
ReplyDeleteThe biology concept that is addressed in this chapter is that the combination of rotating the head and then going in the other direction can cause serious brain damage. This can tie into our biology course because we might be learning about the brain and the effects of car accidents.
My personal interpretation of this chapter was that I learned a lot of information on the dead and cars.Always wear your seat belt or else you you could have serious brain damage if you're in an accident.
I agree with what you say about this chapter. It was compelling to know that using cadavers are more appropriate to test crash impacts and find useful information than what test dummies give you. Possible Biology concepts that may be used is studying the brain, and the amount of force a human body can withstand. The only thing I disagree with is wearing your seat belt. It can harm your body from rupturing things that can be fatal. At the same time, it will not save you from side impacts, so wearing a seat belt may not be the best option.
DeleteThis chapter was one of the more interesting chapters for me. I wasn't really 100% sure if they did use human cadavers for crash tests, but now I know. I think that using actual human bodies for crash testing can make results much more accurate to what could happen to a living human. Dummies are also effective but I dont think that they would ever be able to match the real thing. In this chapter I was able to learn many things including all the different ways that researchers test to ensure a car would be safe enough for a living person to drive and I learned that brain damage was one of the major culprits of being in a car crash, I would have thought it to be broken bones or spinal injuries.
ReplyDeleteI would have to agree and disagree with you. I would agree with you because I do see that if real humans were used we would get a much more accurate result from using a living human being. But I would have to disagree with you because I think using a real human would be bad, chances are they can even die because we don't necessarily know how much force a living human can sustain. In this case it would be more beneficial to use a cadaver where they cant feel pain and there can be something to show how much pain a real human can sustain.
DeleteI agree with both of you in a way. Alex you're right about how we dont know the amount of trauma a human can sutain in a car crash but logically this is as close as we can get without putting someones life in danger, so we use these dummies as our best estimates.
DeleteI found chapter 4 of "Stiff" to be a bit underwhelming in terms of attention-grabbing as it seemed to be more focused on the studies and repercussions of using cadavers as crash dummies and the author's telling of her experience at a cadaver research site.
ReplyDeleteAn anatomy concept covered in this lesson is how durable parts of the human body are to traumatic impact or force.
This chapter focuses on the use of cadavers as crash test dummies in order for car manufacturers to determine different safety measures. Significant parts of the chapter include a bit of history of cadaver research (which in itself includes a case of attempted political intervention) and the author's experience of being at an actual cadaver research site.
I don't completely agree with you since I found this chapter very interesting and I was able to learn something new, but I do agree with you on the description of the chapter and its significant parts.
DeleteI completely agree with you, this chapter is very luring. It actually one of my favorite chapter. Before I didn't agree with cadaver testing. Now I'm 100 % for it. I feel, that because of cadaver being tested cars are now more safer than they were lets say in the 19 century.
DeleteI found this chapter interesting because i believed they only used test dummies for a crash simulator. I never came to think they used actual dead bodies for that. At the same time I think that's great because with a real body we can actually analyze what happens in reality. Real skin, organs, bones, etc. To me it became apparent that the biology concept in this chapter would be testing the human body.
ReplyDeleteIt's funny how some facts can surprise you. When you think of donating bodies for science you believe that its just using organs or studying in a lab on a table but these are cadavers in action. I definitely understand your point of view. And all we want in science is accuracy so thats probably why we use the caddavers as dummies like you mentioned.
DeleteI can totally relate to my reaction with you Ashley, I feel because cadavers are being used as dummies, car manufacturers are able to determine different safety measures and improve the vehicle it self. It true too what you say Paula like when one donates their body to science you only think that it'll be used for organ transplants etc. But now that I know its going to be used for experiments to better improve vehicle safety I feel like I would feel be more comfortable donating my body to science than letting it go to waste.
DeleteThis chapter surprised me because I learned that cadavers are used as crash dummies other than just dummies. I just thought that car companies use plastic human like dummies to test the protection the car exerts when it crashes so the human being would mostly not die but have a few injuries because of all the commercials I have watched in the past. But I was wrong. Mary Roach wrote, "A dummy could tell you how much force a crash is unleashing on various dummy body parts, but without knowing how much of a blow a real body part can take, the information is useless." Cadavers are used to test the impact from the front, rear, and back of these test cars being made. The concept would have probable been the force of damage taken on the cadavers and how the cadaver's dead body would have taken the impact externally and internally. This chapter explains the use of cadavers as crash test dummies in order for car companies to determine safety measures and damage impact of how a real living human would take.
ReplyDeleteI was under the same impression as you about car companies solely using dummies for crash tests. It makes much more sense to use cadavers as it gives car manufacturers important information about how to make vehicles keep drivers safe in certain types of collisions.
DeleteI was also amazed when I read that cadavers were used as crash dummies. I, now, fully understand their significance in the tests. They are much more useful than I thought.
DeleteThis was probably one of the most surprising chapters of them all, because I would have never thought that cadavers would be used to test out car crashes. Obviously now I realize using test dummies would not give you the details needed to create a safe vehicle in the chance of an accident. Biology plays an important role in crash tests, as vital organs and other body parts need to be protected in order to prevent death or fatal injuries. I personally found myself going, "Ooohh!" after realizing what Mary Roach meant after naming the title "Dead Man Driving". I thought it could have meant testing out sudden heart failures or something, so I felt kind of silly after finding out what it truly meant. I felt even more silly when I realized the text on the first page wrote, "Human crash test dummies and the ghastly, necessary science of impact tolerance".
ReplyDeleteThat's when I realized that I skipped some pages after picking the book back up from where I left off.
Maybe I should stop dropping my books.
Ha, I do gotta say this chapter puts the book into play in what a human body reacts to and can be used to find out about every day situations. But the sentence you wrote "Human crash test dummies and the ghastly, necessary science of impact tolerance", definably makes perfect sense, if you sum up the whole chapter into one sentence this would probably be it.
DeleteI was interested in this chapter at first because of the name "Dead Man Driving", but I figured out that they actually used cadaver crash test dummies. I always thought that the only crash test dummies were the real dummies (plastic and metal ones) to test G loads. If you are testing for broken bones and concussions than a cadaver is a much better choice since a crash test dummy doesn't have a brain. I found it interesting how hard of a time the workers were having putting the cadaver in the car. It ties into biology because when they did the tests the were seeing how far the human body would go in a car crash without injury or death.
ReplyDeleteYes, I also believed that in test crashes, only test dummies were used, and it was in fact intriguing that the most difficulty the team had with the cadaver was such a small thing as positioning it.
DeleteI do got to say this chapter might have a silly title, but makes you want to read on, but unlike then, we use fake life sized crash dummies with computers to measure the amount of G loads a crash forces upon the dummy, but tho one thing about this is, you can't measure if someone was to brake a leg like what you said, so i would believe cadavers might be a better test dummy to test the possibility for broken bones and so on.
DeleteTo start off this chapter has an attention grabber title. I never knew that they used Cadavers to test crashes. So that fascinated me the most in this chapter. In this chapter it explains the impacts on your brain when in a collision. Cadavers are a great replacement next to real practice dummies. Although practice dummies are good to test on to. It does not necessarily show the damage the body will undergo. It relates to biology to by showing the ways it can effect the brain.
ReplyDeleteI agree that this really is a fascinating chapter especially as they describe just exactly what happens to the cadaver during impact. Also, it's true that the best way to test vehicles is with cadavers which is the closest they can get to a live human
DeleteThis chapter is also one of the most interesting chapters in my opinion. The reason why is because I would have never thought that cadavers would be used as crash dummies. Also, I enjoyed the fact that with the cadavers being used for the test that we could figure how much force a cadaver can hold.
ReplyDeleteA biology concept is that we can simply figure how much force and pressure a human cadaver can sustain in order for a human to live from a motor crash.
My personal interpretation of the text is that it mainly focuses on Mary Roach heading to a crash test place, where cadavers are crash test dummies and they are used to find out how much force from a crash a human can sustain in order to make vehicles a lot more safer in the future.
I too believe that it is shocking to use cadavers as crash dummies, it just seemed a really far fetched idea; however, it's great that they are being used for the benefit of the public.
DeleteThis chapter mainly captured my attention because it discuses the usage of cadavers to test automobile crashes. Although I knew that for cars to be the way they are now many tests must have been executed to ensure their safety, I just never made the connection nor imagined that cadavers were involved, instead I always believed that test dummies were used for these experiments. However, it makes perfect sense since using dummies or animals would not yield as accurate results as cadavers would. It's incredible all the experiments that have to be done on the cadavers to try to find the injury threshold by testing the limits of human resistance and the damage caused by such impacts. Also, the autopsies that must be preformed to determine the internal damage to the tissues, blood vessels, and internal organs as well as bones. Probably the most impressive part of the chapter though, was hearing about the scientists that were so passionate about their research that they risked their lives undergoing various crashes in hopes of also finding the injury threshold, and making automobiles safer for the public.
ReplyDeleteThe chapter, Dead Man Driving, was an informative chapter. The chapter comprised of information regarding driving safety. Roach was able to see cadavers being used as car crash dummies. The cadavers allowed the scientists to discover the amount of impact the human body can take, mainly the shoulder, coming from the side. The cadavers were immensely important when being tested for cars. They allow for progression in car safety. It will prevent more deaths and serious injuries while in a car. Cars will also become more efficient and safer for a person to drive. For most of my life I thought that car company's tested there cars using fake dummies. After reading this chapter, I understood why actual bodies were used. It allows for maximum results.
ReplyDeleteCadavers as crash dummies was pretty funny to me seeing how in commercials we always see like stuffed dummies and not people. I do though agree that it does prevent more injuries in car accidents because we are able to prevent that with the test crashes.
DeleteIn this chapter I was very surprised in the title “ dead man driving”. Honestly, I did not know what to expect in this chapter. This chapter describes how cadavers are used with car crash studies. I never would have known that cadavers were involved in the studies on crash test. I was amazed in how cadavers (such as um006) are used to figure out how much force a human can handle without serious injuries. All of this information studied is then used for other parts and details of a car to be made or improved. I believe it is intelligent for studies to happen on cadavers rather than dummies for the reason being more accurate results. I also learned that at specific times, animals were also used to test other impacts in car crashes. Like many chapters in this boo, I learned many new things I probably never would have learned without reading this book.
ReplyDeleteThis chapter was mainly focused on safety in driving and how cadavers were used as crash dummies. This really proves the cadavers endless use to not only living but to help bebing safety to the living. I always believed that crash dummies were completely artificial but I guess that the best way to find out about safety is by using people to test it. The bumps and bruises examined to predict the damage that would be done to a consumer would relate to a topic that we will cover in this class. This chapter hit personally with me since I was in a very bad car accidents so I can imagine how it would feel to put an actual person to test the crashes.
ReplyDeleteI agree with your opinion on how cadavers have endless uses, and I too thought crash dummies were artificial.
DeleteI found this chapter very interesting because it didn't have to do with cadavers being used by physicians but by car companies. I also did not know cadavers were used as est dummy's, it makes sense to use them because they're actual human bodies. The anatomy concept in this chapter has to do with the durability of the human body; the bones especially. My interpretation of this chapter was that it was about how cadavers are applied to car safety. If it weren't for cadavers being used as test dummies for cars most people would die in car accidents.
ReplyDeleteI agree this chapter was not particular about a human cadavers getting dissected but being use to test cars.
DeleteI agree, I think cadaver really don't get the respect they deserve because without them more car crashes would up ended with fatalities.
DeleteThis chapter in stiff was really about car companies used cadavers to test out cars. Which was something I didn't know, I thought test-dummies were plastic bodies not actually cadavers.My interpretation of this chapter is how cadavers contributed to making a more safe driving environment. These studies allowed car companies to make safer cars for use to drive today.These chapter relates to anatomy and how much damage a human body can take.
ReplyDeleteThis chapter went over how cadavers and dummy's are used to test the various outcomes of car accidents and implement the data to ensure safety in vehicles via airbags or seat belts. What I found the most interesting however is how vehicle history progressed over time. The author explained that before there were no windshields, to lethal and dangerous windshields, to safe windshields. I also found it interesting how the steering wheels of old cars would crush the body and damage vital organs. Also, the stand of the steering wheel would directly impale the heart which lead to collapsible stands. In this chapter, it is clear that vehicle safety has come a long way and it was because of various dummy's and some cadavers that made that sacrifice.
ReplyDeleteIt is nice to see how far vehicle safety has improved over time. I wasn't aware that some would have no windshields and that steering wheels were at such high risk of killing someone if they got involved in an accident. Cadavers have really contributed to vehicle safety over time and I think they should deserve more credit among others.
DeleteHa ha, "cadavers that made that sacrifice." The impact cadavers have had on car safety is evident through the changes implemented in car manufacturing. I mean, we went from the 1970 Datson 240Z to the 2014 Nissan 370Z thanks to these dead meats!
Deletethis chapter had to be one of my favorites because as much as i am not interested in cars all the reading about how they came to make cars so safe made me want to know so much more about cars and how they come to be built. also another thing that was very interesting was the think about swinging your head can give you a bad concussion that was very surprising to me and i really made me think more about how serious and fragile your body is. In this chapter there were some little footnotes that also came to my attention talking about how back in the days cars were bought because of the way they looked so people didn't care that they would save their lives.
ReplyDeleteI agree, it's sad that back in the day people cared more about the look of the car rather than the safety it would offer. The Survival Car would've saved a lot of lives that were lost in fatal accidents which is rather unfortunate. It is interesting how swinging you head at a fast motion, like in a car crash, could put you in a coma. It does remind you that although the human body could withstand a lot, it can also be damaged easily.
DeleteI had no idea that cadavers and cars would be related. The cadavers were used to help determine the safety of cars. There was also a lot of information about certain fatalities that can occur in a car crash. It makes sense to use the actual dead bodies. I think its amazing and unbelievable that some people actually volunteered to be used as dummies. I felt really bad when I heard read that animals were used in automotive impact testing. Pigs are very similar to humans. Since they have a similar organ setup as human beings, they were used more regularly.
ReplyDeleteI was shocked as well when I read there were volunteers for these tests. They must have been incredibly passionate about their research and they may have cared for people to be safe. They are kind of like heroes in a way in my opinion.
DeleteLearning that there were indeed volunteers for such car tests had me in shock as well. It takes conviction to risk one's own life in order to progress in car safety. Sad, because I don't think stunt men are as cool anymore.
DeleteIn the fourth chapter of Stiff, I was shocked to learn that cadavers would come of use for car crashes. Usually, commercials show dummies crashing into walls at fast speed to show its safety advantages so I assumed that dummies would be used for that type of research. Then again, it would be unsettling seeing a corpse on television on a car commercial. The biological concepts found in the chapter had to do with certain injuries that could be presented in car crash and how the cadavers help a lot with preventing another fatal car crash by using them as their test subject. I found that the idea of using pigs for the research was really smart with them having organ setup similar to humans. Overall, I enjoyed the chapter.
ReplyDeleteWho could have known that cadavers were used in automobile companies to see what type of car crash damage could be done to a human being. Dummies are use to see how mush force is put on a dummies body part when it crashes. The first windows use in cars were glass window which were easily broken into by the drivers head giving him gruesome cuts. Then came tempered glass which was strong enough to keep the head from going through the class but it could cause serious brain damage. Brain damage is the major culprit ( as Mary Roach says) in car accidents. Its the brain going in one direction then going rapidly back that cause brain damage. Then came in the type of steering wheel that would hit the chest of a person and kill them when they hit it with enough force. Of course this was before the seat belt was invented. Also the type of seat belt could have killed you in a car crash.
ReplyDeleteThis chapter I found to be very interesting because the logic it held, behind the reasoning of using cadavers as crash test dummies. I was like many who thought dummies was used in in car crash test. But I'll prefer to use cadavers, because it will give crush test more accuracy. Because the damage the cadavers will receive can simulate what a living person can wittiness in a car crash. So I believe its better to test a car with someone already dead instead of recalling a car that had a low crash-accident rate.
ReplyDeleteThis chapter of the book was really informative because i never knew that cadavers where use for crash test i knew they used crash test dummies but i never knew that they use crash cadavers, I think that a cadaver gives a much better understanding of the forces the human body is experiencing when a car crashes head on to a wall.
ReplyDeleteI always thought that dummies were used for crash tests to see the damage the car would give to the person, I never knew that cadavers would be used. On top of that, I also didn't know that the cadavers would be used with such high tech equipment, and it would be used to see the exact force a car would give to a passenger/driver. I think this is a very important and effective practice.
ReplyDeleteI loved this chapter because it talks about cadaver being used as test dummies .I never knew that they did that sort thing with cadavers honestly. I was so interested after reading the title of this chapter but i was kind of disappointed with what i read. I was expecting something way more exciting.
ReplyDeleteChapter four mostly talks about how cadavers are being tested on the impacts on test crash impacts and the effect that it has on their body. Roach states that cadaver testing is one of the most accurate testing since they are a human being as well as the fact that they have the ability to feel no pain. Also, because of cadaver testing on car accidents, it has improved safety measurements when creating a car, decreasing the number of car accidents that happen.
ReplyDeleteWho would’ve thought? Cadavers and cars… think you know a (dead) guy. I was deflected with awe after having read, “Over the past sixty years, the dead have helped the living work out human tolerance limits for skull slammings and chest skewerings, knee crammings and gut mashings: all the ugly, violent things that happen to a human being in a car crash” (Roach 87). I now realize that the process was vital for the progression of car safety. Without advancements in car safety... It wouldn’t be safe. All in all, I felt like a dummy while reading this chapter. Ha. Ha.
ReplyDeleteThe chapter got my attention because I have always heard that they had car-testing dummies to test all of the safety issues before the car is manufactured to the masses. As I started reading the chapter, I realized that I was completely wrong. Cadavers are actually used to test how much force human body parts can take in impacts from all sides. The chapter also explains how you can get a concussion from hitting your head on something or whipping it back and forth really fast. This relates to biology because it is testing the safety of car impacts with human and animal cadavers.
ReplyDeleteReading this chapter I learned that cadavers weren't just used for analysis and research in a science lab but for another thing that I would've never thought about! They are used as dummies to test out car impacts! They are more specifically used to examine how strong human body parts are against impacts. I found this so interesting because it was honestly something that I previously had a knowledge about.
ReplyDelete
