Superficial flexor of fingers

Superficial flexor of fingers , m. Flexor digitorum superficialis, covered in front m. Palmaris longus and m. Flexor carpi radialis, leaving on it a trace in the form of furrows. The muscle has two heads: a) a humerus capit, caput humeroulnare, long and narrow, - from the medial epicondyle of the humerus and the coronoid process of the ulna; B) radial head, caput radiale, wide and short, - from the proximal part of the anterior surface of the radial bone. Both heads, uniting in the common abdomen, end with four long tendons. The latter, passing to the brush, lie in the canal of the wrist and are attached to the base of the middle phalanges from the index finger to the little finger. At the level of proximal phalanges, each tendon is divided into two and therefore is attached not in one, but in two points - along the edges of the base of the middle phalanges.

Function: Envelopes the middle phalanges of the fingers from the index finger to the little finger.

Innervation: n. Medianus (CVII - ThI).

Blood supply: aa. Radialis et ulnaris.
