This section passes through the end of the muscular portion of brachioradialis ( 1). The muscle is now primarily tendinous. As the wrist is approached, the muscles of the forearm begin to form tendons, which insert on the wrist or in the hand.

The deep branch of the radial nerve (13) supplies the extensor muscles of the forearm, and the median nerve (2) supplies all but one and one half muscles of the flexor muscles of the forearm. The ulnar nerve (23) supplies two forearm muscles, flexor carpi ulnaris (22) and approximately one half of flexor digitorum profundus (21).
