• Anconeus — A small, triangular muscle located on the posterior aspect of the elbow joint, extending between the lateral epicondyle of the humerus and the olecranon of the ulna. It acts as a weak synergist of the triceps brachii muscle, with the functional role of assisting in the extension of the forearm and stabilizing the elbow joint during rotational movements.
