The flexor carpi ulnaris (FCU) muscle is a muscle of the human forearm that acts to flex and adduct the hand. ==Origin and insertion== Flexor carpi ulnaris muscle arises by two heads - humeral and ulnar, connected by a tendinous arch beneath which the ulnar nerve and ulnar artery pass. * The ''humeral head'' arises from the medial epicondyle of the humerus by the common flexor tendon. * The ''ulnar head'' arises from the medial margin of the olecranon of the ulna and from the upper two-thirds of the dorsal border of the ulna by an aponeurosis. Its insertion is into the pisiform bone and then via ligaments into the hamate bone-g pisohamate ligament- and 5th metacarpal bone-forming pisometacarpal ligament. Its action is to flex and adduct the wrist joint. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「flexor carpi ulnaris muscle」の詳細全文を読む スポンサード リンク
