Encyclopedia > Flexor carpi ulnaris muscle

In anatomy, flexor carpi ulnaris muscle is a muscle of the human forearm that acts to flex and adduct the hand. Anatomical drawing of the human muscles from the Encyclopédie. ...


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. The ulnar nerve is a nerve that in humans runs down the arm and forearm, and into the hand. ... Arteries of the right forearm - anterior view. ... The humerus is a long bone in the arm or fore-legs (animals) that runs from the shoulder to the elbow. ... The ulna (along with the radius) is one of the two bones in the forearm. ... Aponeurosis is the singular of Aponeuroses Grays Anatomy states that Aponeuroses are flattened or ribbon-shaped tendons, of a pearly white color, iridescent, glistening, and similar in structure to the tendons. ...


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.) In anatomy, flexor carpi radialis is a muscle of the human forearm that acts to flex and abduct the hand. ...


Its insertion is into the pisiform bone and then via ligaments into the hamate bone and 5th metacarpal bone, acting to flex and adduct the wrist joint. A ligament is a short band of tough fibrous connective tissue composed mainly of long, stringy collagen molecules. ... The metacarpus is the intermediate part of the hand skeleton that is located between the fingers distally and the carpus which forms the connection to the forearm. ...


Unlike most of the flexors of the hand, flexor carpi ulnaris is innervated by the ulnar nerve. It gets its blood from the ulnar artery.

Rhomboid minor muscle - Wikipedia, the free encyclopedia (278 words)
Muscles connecting the upper extremity to the vertebral column.
Acting with the rhomboid major, both muscles retracts the scapula and rotates it to depress the glenoid cavity.
It is inserted into the base of the triangular smooth surface at the root of the spine of the scapula, and is usually separated from the Rhomboideus major by a slight interval, but the adjacent margins of the two muscles are occasionally united.
