| Anterior compartment of the forearm | |
|---|---|
| Cross-section through the middle of the forearm. (Anterior compartment is at top; posterior compartment is at bottom.) | |
| Latin | compartimentum antebrachii anterius |
| 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[2]:
| 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 (as anterior interosseous nerve) |
| deep | flexor pollicis longus | E | median (as anterior interosseous nerve) |
| deep | pronator quadratus | I | median (as anterior interosseous nerve) |
The muscles are largely involved with flexion and pronation[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].
