Anterior compartment of the forearm

The anterior compartment of the forearm (or flexor compartment)^[1] contains the following muscles:^[2]

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)

Anatomical terminology [edit on Wikidata]

The muscles are largely involved with flexion and supination.^[2] The superficial muscles have their origin on the common flexor tendon.^[2] The ulnar nerve and artery are also contained within this compartment.^[2] 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.^[2]
