Homework for drawing class.
You'll never get anatomy right unless you know how the bone and muscle structure works, so hath my teachers spoken. As a result I spent all weekend drawing skeletons, mostly reproduced from several photocopies our professor supplied us with, so I don't recommend you use these as references for "accurate" skeletal anatomy. Don't come crying to me when your biology teacher roars at you for mislabelling the femur, because I'm only going to laugh and tell you that I told you so.
