• The gracilis (also gracilis muscle, latin: musculus gracilis) is a long, thin, superficial muscle of the medial region of the thigh.

    The gracilis originates from the inferior pubic ramus. The fibers of the gracilis pass vertically downward. The tendon of the gracilis together with the sartorius and semitendinosus form a common plate - pes anserinus that inserts onto the tibial tuberosity.

    The functions of the gracilis are adduction of the femur, flexion and internal rotation of the knee.
