Anterior compartment of the forearm

From Wikipedia, the free encyclopedia

Anterior compartment of the forearm
Cross-section through the middle of the forearm. (Anterior compartment is at top; posterior compartment is at bottom.)
Artery	ulnar artery
Nerve	median nerve (anterior interosseous nerve), ulnar nerve (muscular branches of ulnar nerve)

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

Level	Muscle	E/I	Nerve
superficial	flexor carpi radialis	E	median
superficial	palmaris longus	E	median
superficial	flexor carpi ulnaris	E	ulnar
superficial	pronator teres	I	median
superficial (or intermediate)	flexor digitorum superficialis	E	median
deep	flexor digitorum profundus	E	ulnar + median
deep	flexor pollicis longus	E	median
deep	pronator quadratus	I	median

• "E/I" refers to "extrinsic" or "intrinsic".

The muscles are largely involved with flexion and pronation. The superficial muscles have their origin on the common flexor tendon.
