Flexor carpi ulnaris

Origin Medial epicondyle (common flexor tendon)
Insertion Pisiform
Action(s) Flexion of wrist
Nerve Supply Muscular branches of ulnar nerve
Arterial Supply Ulnar artery
Physical Exam  
Clinical Importance  
Disease States Ulnar entrapment by the the aponeurosis of the 2 heads of the flexor carpi ulnaris (FCU) muscle may cause cubital tunnel syndrome.
Discussion Tendon:

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.)

Exercises:

The muscle, like all flexors of the forearm, can be strengthened by exercises that resist its flexion. A wrist roller can be used and wrist curls with dumbbells can also be performed.
