The humerus is a long bone in the arm that runs from the shoulder to the elbow. It connects the scapula and the two bones of the lower arm, the radius and ulna, and consists of three sections. The humeral upper extremity consists of a rounded head, a narrow neck, and two short processes (tubercle...

Muscles of both the upper arm and forearm control movement of the forearm. The biceps brachii flex the forearm and work with the supinator of the forearm to rotate it so the palm faces upward. The pronator teres and quadratus control pronation, or rotation of the forearm so that the palm faces do...
