Shoulders and Arms

•The forearms are composed of two bones, the radius and the ulna.

•Weight or pressure from the hand is levered through the wrist to the radius

•The radius is the primary bone at the wrist and the ulna the primary bone at the elbow

•This structure gives the forearm lightness and mobility, and provides attachment sites for the many muscles of the hands.
