The sartorius muscle (m.sartorius) begins on the superior anterior iliac spine. The muscle crosses obliquely from top to bottom and medially the anterior surface of the thigh. It is attached, passing into the tendon stretching, to the tuberosity of the tibia and to the fascia of the shank.

At the attachment site, the tendon of the sartorial muscle fuses with the tendons of the thin and semitendinous muscles and forms a fibrous plate of triangular shape, the so-called superficial goose paw (pes ansennus superficialis), under which there is a goose pouch bag (bursa anserina).

The function of the sartorius muscle: flexes the thigh and the shin, is also involved in turning the thigh outward.

Innervation of the sartorius muscle: femoral nerve (LII-LIV).

Blood supply of the sartorius muscle: muscle branches of the femoral artery, lateral artery, enveloping the femur, descending knee artery.
