Back of right upper extremity. (Anconeus labeled at bottom center.)
Posterior surface of the forearm. Superficial muscles. (Anconeus visible at center right.)
Details
Origin
Lateral epicondyle of the humerus proximally
Insertion
Lateral surface of the olecranon process of the ulna and the superior proximal part of the posterior ulna
Artery
Deep brachial artery, recurrent interosseous artery
Nerve
Radial nerve (C5, C6, C7, C8, and T1)
Actions
It is partly blended in with the triceps, which it assists in extension of the elbow. It also stabilizes the elbow during pronation and supination and pulls slack out of the elbow joint capsule during extension to prevent impingement.

Anatomical terms of muscle
[edit on Wikidata]
The anconeus muscle (or anconaeus/anconæus) 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,[4] while others consider it part of the posterior compartment of the forearm.[5]
The anconeus muscle can easily be palpated just lateral to the olecranon process of the ulna.[6]
