For me, it was not just the memorization of body parts, but the physiology (how the body works). They start as low as the atom, a bit of chemistry (not heavy, though), but it was far detailed than what I cared for and what I use in life. If you have a good professor that really breaks it down and makes it interesting, that is a good thing.
I am not a science oriented person, so, I had to really work hard at it. It was not until after I graduated where I found a decent book that simplified the teaching...none of the terminology was lost, but, it was a sensitive author that gave real life examples of what was happening for me to now have a basic appreciation. The name of the textbook is The Human Body in Health and Illness by Barbara Herlithy (you may wish to order this book ahead of time-even used and use it in addition to the text they give)- http://www.amazon.com/Human-Body-Hea...0736738&sr=8-1
I dedicated a great deal of time to anatomy, but I did more memorizing than comprehending at that time, which frustrated me. We each have our own learning styles. For me, break it down simple, main points and correlation to real life is what gets me to really understand and appreciate it. I think I was also frustrated because while I know for a fact that anatomy and physiology is an important component, I never felt that the presentation of the class had to be made so complicated. I had two idiot professors at that. You may find that you will excell in those classes. My advice, however, is not to take it with other difficult classes, and if I had a choice, I would have taken it alone. Make cue cards, use highlighters, read again and again, consider using the book I suggested as the book to read on the side to get the basic picture. If they had used the one I suggested, I would have probably gotten a higher grade. In any event, it is over, I am an LPN, and I am fine with that. Best of luck!
