I am glad there are some people who like anatomy, but definitely it is boring from a physicist point of view. Anyway, if you want to learn or just curious about anatomy www.getbodysmart.com is a good place to look for. There you can find all main muscles, bones, nerves, respiratory system, etc. And you can see how they move and or interact in your body in flash animations. There are also quizzes for who want to test their own skills. Excellent content!
