Muscles that Move the Forearm

Most forearm movements are produced by muscles that connect the radius or ulna to the humerus or pectoral girdle. A group of muscles located along the anterior surface of the humerus flexes the forearm at the elbow, whereas a single posterior muscle extends this joint. Other muscles cause movements at the radioulnar joint and rotate the forearm.

The muscles that move the forearm are shown in figures 9.29, 9.30, 9.31, 9.32, in reference plates 63, 65, and are listed in table 9.8, grouped according to their primary actions. They include the following:
