The anterior compartment of the forearm (or flexor compartment) contains the following muscles:
Level Muscle Extrinsic/Intrinsic Nerve superficial flexor carpi radialis extrinsic median superficial palmaris longus extrinsic median superficial flexor carpi ulnaris extrinsic ulnar superficial pronator teres intrinsic median superficial (or intermediate) flexor digitorum superficialis extrinsic median deep flexor digitorum profundus extrinsic ulnar + median (as anterior interosseous nerve) deep flexor pollicis longus extrinsic median (as anterior interosseous nerve) deep pronator quadratus intrinsic median (as anterior interosseous nerve)
The muscles are largely involved with flexion and supination. The superficial muscles have their origin on the common flexor tendon. The ulnar nerve and artery are also contained within this compartment. The flexor digitorum superficialis lies in between the other four muscles of the superficial group and the three muscles of the deep group. This is why it is also classified as the intermediate group.
