bhenry,
as old as it sounds .. flashcards is what works for me. I had to do a lot of muscle memorization (origins, insertions and actions) and the way I did it was made up a 3x5 card for each one. I'd play games with myself, or have someone test me. I went over them hundreds of times. I carried the stack of cards with me at all times and when I had an extra minute or two I'd pull out a few and learn them.
I also had anatomy coloring books that I would color in when working with specific parts.
I think when dealing with this stuff, it is literally rote memorization.
