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

| Anatomical terminology | |
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) |
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]
