I'm starting human anatomy next week, and would love to get a sticky started to keep each other sane. I'm a bit nervous about starting this class, as I really need an A, but work full-time and will also be taking abnormal psych. It's going to be a lot of work!
Let's help each other out through this forum! :welcome:
So, when are you starting, where are you taking it, and how are you feeling?
I record each class, and then listen to them when I'm doing laundry, in the car, ect. It has really helped me a lot. I also like to use the companion website that the text has
Besides my gazillion of index cards, which I carry with me and study when I have a few minutes, I have also found the textbook website to be a great resource, as heartaflame has suggested. My textbook's website has all kind of activities, from matching to true/false, to labelling diagrams to crossword puzzles. I have found that doing all of them is really helpful. And there's no penalty for a wrong answer, since you're doing this just to learn. :) If you bought a used text and the access code is no longer available, spend the 30 bucks or so to get access to the website! My access lasts until March of 2009, so that should get me through A&P I and II.
Wow, this is going to be tough! My professor seems very cool, she even told us that if we have family obligations that conflict with class, she expects us to be with our family. They are number one. I have never heard that from a professor before! She said we will need about 20 hours a week study time for this class and I don't think she was exaggerating.... I have a headache from trying to learn all the vocabulary today! We have labs once a week so I haven't done that yet but we'll be doing 4 of them Monday! yikes! It's exciting though...
sorry got confused! my homework was to compare and contrast negative and positve feedback (homeostasis)..need help ! please! thank you!!
The easiest way I've heard it described is that negative feedback takes something closer to the norm, making the body more stable. 98% of feedback is negative. Positive feedback moves the body away from the norm, toward a more unstable environment. Examples are blood clotting and labor.
Did your book/professor use the example of your household thermostat for negative feedback? That leads me to believe that the body getting a fever to kill off a virus would be positive feedback. Can anyone else comment on this?
need help w/ my homework, i can't seem to think straight w/ all these new language we're learning. i'm soo confused w/ homeostasis, need example of 1 negative feedback and 1 positive feedback...all your help would be greatly appreciated...i need to study this weekend since i have a quiz on tuesday for both lecture and lab wahahhahaha
thanks a lot in advance!!
Just remember the majority of feedback mechanisms are negative and that they are opposite of the initial change in the system. It repairs the body to original state. The positive feedback mechanism intensifies the change in the body (example: blood clotting or oxytocin during childbirth)
I am four weeks into my AP1. Last Saturday, we had our first exam. 71 question and I am pretty sure I got right about 68 of them...if I do not get an A, I will miss it by point or two. I have to say that my professor is great, we do not even have to study the book, although it is recomended...He gives us study material (notes) for each exam, Power Point presentation and we study from that. I did not even study for the first two weeks or so, but the week before our first exam, I studied for about 2-3 hours each day and I am pretty sure, I will get an A.
My approach is, I wrote all of my notes on flash cards, I recorded my notes and listen to them each day, and I write, write, write when I study...for example, when I study/read about cartilage, I will then write down everything I know about it...do some more (glands etc.) and then repeat all over...Worked great for me.

Someone already gave the most common example of negative feedback, which is temperature control. You can't go wrong with that example. Childbirth is a great example of positive feedback, and so is blood clotting after an injury to the skin. The blood clotting example is the most common one you see in textbooks.
Best of luck!
