Muscle Quizzes & Trivia
A quiz on the actions, insertions, and origins of the major muscles of the lower appendicular skeleton. It kind of sucks, but see for yourself. The questions would have worked better as fill in the blank, but I was too lazy to enter all the possible answers that might be partially or fully right. Make sure to check the explanations as there are all the cool details in there.
