The biceps brachii, brachialis, and brachioradialis ( which attaches distally ) act to flex the elbow . ( The biceps do not attach to the humerus . ) The triceps brachii and anconeus extend the elbow, and attach to the posterior side of the humerus.

It gives off, near its origin, the interosseous recurrent artery, which ascends to the interval between the lateral epicondyle and olecranon, on or through the fibers of the Supinator, but beneath the anconeus, and anastomoses with the middle collateral branch of the profunda brachii, the posterior ulnar recurrent and the inferior ulnar collateral.

They found that the only possibility was that the bumps could be an attachment scar for the " M . anconeus " muscle, which is unlikely, because this muscle normally attaches to a smooth surface without marks or bumps on the underlying bone, and argued that the most likely explanation for the bumps was their initial interpretation as feather quill knobs.

The "'Epitrochleoanconeus muscle "'( "'anconeous epitrochlearis muscle "', "'anconeus-epitrochlearis "'or "'anconeus sextus "') is a small accessory muscle of the arm which runs from the back of the inner condyle of the humerus over the ulnar nerve to the olecranon.

The radial nerve and its branches provide motor innervation to the dorsal arm muscles ( the triceps brachii and the anconeus ) and the extrinsic extensors of the wrists and hands; it also provides cutaneous sensory innervation to most of the back of the hand, except for the back of the little finger and adjacent half of the ring finger ( which are innervated by the ulnar nerve)
