from Greek: αγκων ("ancon") - elbow
Synonyms: anconeus, elbow muscle, elbow tubercle muscle
German: Musculus anconeus
The origin of the anconeus muscle is the lateral epicondyle of the humerus (bone of the upper arm). Some fibers additionally originate in the ulnar collateral ligament as well as in the capsule of the elbow joint.
The anconeus muscle serves as mild extensor muscle of the elbow joint and supports the triceps brachii muscle in this. Moreover, it takes part in the direction of the proximal ulna during pronation movement. Additionally, as capsule tightener, it prevents the entrapment of parts of the elbow joint capsule.
