The Flexor Carpi Ulnaris Muscle is one of the muscles of the human forearm that flexes and adducts the wrist. It is located on the medial side of the forearm and is the most medial of the superficial muscles in this region.

Origin and Insertion[edit | edit source]

The Flexor Carpi Ulnaris originates from two heads - the humeral head, which arises from the medial epicondyle of the humerus, and the ulnar head, which arises from the medial margin of the olecranon and the upper three-quarters of the posterior border of the ulna. The muscle inserts into the pisiform bone, the hook of the hamate, and the base of the fifth metacarpal bone.

Innervation[edit | edit source]

The Flexor Carpi Ulnaris is innervated by the ulnar nerve, which is responsible for the muscle's flexion and adduction actions at the wrist.

Function[edit | edit source]

The primary function of the Flexor Carpi Ulnaris is to flex and adduct the wrist. It also assists in the flexion of the elbow joint.

Clinical Significance[edit | edit source]

Damage to the ulnar nerve can lead to a loss of function of the Flexor Carpi Ulnaris, resulting in a reduced ability to flex and adduct the wrist.
