| Gray's | subject #125 454 | |
| Origin: | lateral epicondyle of the humerus proximally | |
| Insertion: | lateral surface of the olecranon process and the superior part of the posterior ulna distally | |
| Artery: | deep brachial artery, recurrent interosseous artery | |
| Nerve: | radial nerve (C7, C8, and T1) | |
| Action: | It is partly blended in with the triceps, which it assists in extension of the forearm. It also stabilises the elbow and abducts the ulna during pronation. | |

The anconeus muscle is a small muscle on the posterior aspect of the elbow joint.
Some consider anconeus to be a continuation of the triceps brachii muscle[1][2][3].
Some sources consider it to be part of the posterior compartment of the arm, while others consider it part of the posterior compartment of the forearm.
