I've been working really hard on drawing a picture for my brother so I only spent half an hour studying this early instead of the normal hour or so. As far as massing the whole girdle, I'll save that study for when I go more in depth on the muscles. For now I just studied the bones that are involved in the girdle. They are the clavicle in the front, the scapula in the back, the spine of the scapula, and the acromion process. These form a sheild and protect our humerus and the ball and socket joint. I have two triangles dotted in because the book I was reading out of was explaining how to build the this area of the body using two triangles. Enjoy!!
