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	Enter physical examination maneuvers for muscle
Clinical Importance	Enter clinical importance of muscle
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.
