Okay, you failed anatomy 101, but you still want to know more about anatomy of a human. Well, you can simply watch this video tutorial that will show you how to cut up a human cadaver, dissecting its leg and foot, getting a good look at the science of the muscles.
Don't try and find your own corpse, just beware that there are three compartments to the leg, which are the posterior, the lateral, and the anterior compartment. You'll get a look at not just not muscles, but the nerves and ligaments, too, to name a few.
This is very informative for medical students in need of cadaver dissection instructional videos.
