Related to Antibrachium: Antebrachium
the part of the human upper limb from above the elbow to the hand. The radius and ulna are the skeletal foundation of the forearm and form the distal and proximal radioulnar articulation, which make possible rotational movements around the axis of the ulna. The bones of the forearm serve as points of attachment of the muscles that move the shoulder, wrist, and fingers. Deep vessels and nerves are found in the intermuscular spaces of the forearm. These include the radial and ulnar arteries and veins and the radial, ulnar, and median nerves. The subcutaneous fatty tissue of the forearm contains superficial nerves and veins. Traumas can involve not only injury to soft tissue but also possible simple or compound fractures of one or both bones of the forearm; frequently, the lower joint end of the radius is involved.
