A muscle seated at the upper and anterior part of the forearm. It is long, flat, and larger above than below. It is attached, above, to the inner tuberosity of the humerus and to the coronoid process of the ulna. Thence it passes obliquely downwards and outwards, and terminates at the middle of the outer surface of the radius. It causes the radius to turn on the ulna, to produce the motion of pronation. It can, also, bend the forearm on the arm, and conversely.
