It's about repetition. If you draw the muscles, bones and skeletons enough, it sticks in your mind. Using pictures to remember is the most effective way to learn something, and drawing them will help more than just reading or looking.
I can draw a whole skeleton pretty flawlessly, as can most experienced artists; It's all about repeating yourself until you become so sick of it that you do it without thinking.
