Definition

Muhammad A. Javaid

The ulnar head of flexor carpi ulnaris muscle is its second origin that arises via an aponeurosis from the medial aspect of the olecranon process and the adjoining posterior border of the ulna. This head is particularly significant as it forms an arch with the humeral head, creating a passageway for the ulnar nerve to enter the forearm.
