Flexor carpi ulnaris muscle

From Freepedia

In anatomy, flexor carpi ulnaris muscle is a muscle of the human forearm that acts to flex and adduct the hand.

Flexor carpi ulnaris muscle arises by two heads - humeral and ulnar, connected by a tendinous arch beneath which the ulnar nerve and ulnar artery pass. The humeral head arises from the medial epicondyle of the humerus by the common flexor tendon; the ulnar head arises from the medial margin of the olecranon of the ulna and from the upper two-thirds of the dorsal border of the ulna by an aponeurosis.

The tendon of flexor carpi ulnaris can be seen on the anterior of the distal forearm. On a person's distal forearm, right before the wrist, they will see either two or three tendons. Flexor carpi ulnaris is the most medial (closest to the little finger) of these. (The most lateral one is flexor carpi radialis muscle, and the middle one, if it exists, is palmaris longus.)

Its insertion is into the pisiform bone and then via ligaments into the hamate bone and 5th metacarpal bone, acting to flex and adduct the wrist joint.

Unlike most of the flexors of the hand, flexor carpi ulnaris is innervated by the ulnar nerve. It gets its blood from the ulnar artery.
