The Urinary System: Ureter and Urinary Bladder, The Skeletal System 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. It inserts on the distal phalanx of the thumb.. They both arise from the medial epicondyle, where they share a massive tendon of origin, the common flexor tendon, with two other flexor muscles. The Immune System The flexors allow for the actual bending of the fingers. Anterior interosseous nerve syndrome diagnosis and intraoperative findings: A case report. The ulnar nerve and artery are also contained within this compartment. When contracted, most of the tendons of these muscles are prevented from standing up like taut bowstrings around the wrist by passing under the flexor retinaculum on the palmar side and the extensor retinaculum on the dorsal The Immune System WebThe muscles of the hand are the skeletal muscles responsible for the movement of the hand and fingers.The muscles of the hand can be subdivided into two groups: the extrinsic and intrinsic muscle groups. Conducting System of the Heart (Nervous Impulse Flow) Almost every muscle constitutes one part of a pair of identical bilateral muscles, found on both sides, resulting in approximately 320 pairs of muscles, as presented in this article. Lymphatic drainage of the upper limb occurs via the axillary lymph nodes.[1].
