Definition
The ulnar (or medial) head of the extensor carpi ulnaris muscle originates from the medial margin of the olecranon and the upper two-thirds of the posterior border of the ulna, via an aponeurosis. Other muscles, including the flexor carpi ulnaris and the flexor digitorum profundus, share this origin.
