Extensor carpi ulnaris is a fusiform muscle in the posterior forearm. It spans between the elbow and base of the little finger. This muscle belongs to the superficial forearm extensor group, along with anconeus, brachioradialis, extensor carpi radialis longus, extensor carpi radialis brevis, extensor digitorum and extensor digiti minimi muscles.
Flexor carpi ulnaris is the most medial muscle of the anterior forearm compartment. Learn everything about its anatomy now at Kenhub!
Explore the anatomy and function of the flexor carpi ulnaris muscle, its involvement in hand flexion and adduction, and related health conditions.
The extensor carpi ulnaris (ECU) plays a pivotal role in wrist and forearm function, contributing to both extension and adduction of the hand at the wrist, while also providing essential medial stability.
Flexor carpi ulnaris muscle (FCU) is the most medial flexor muscle in the superficial compartment of the forearm. It can adduct and flex the wrist at the same time; acts in tandem with flexor carpi radialis to flex the wrist and with the extensor carpi ulnaris to adduct the wrist.
The flexor carpi ulnaris is the only anterior compartment muscle that receives full innervation from the ulnar nerve. Origin. Medial epicondyle of humerus, olecranon and posterior border of ulna. Insertion. Pisiform bone, hamate bone, base of 5th metacarpal bone. Function. Wrist joint: Wrist flexion, wrist adduction. Nerve supply.
The flexor carpi ulnaris (FCU) is a superficial flexor muscle of the forearm that flexes and adducts the hand (see Image. Anterior Forearm Compartment Muscles). This muscle is the most powerful wrist flexor and the only anterior forearm compartment muscle completely innervated by the ulnar nerve.
The extensor carpi ulnaris is an essential muscle in the activity of the wrist and forearm that contributes not only to the extension and adduction of the wrist but also to its medial stability. It is most commonly injured in athletes subject to forceful wrist movements.
