what muscles insert on the pes anserinus
Anatomy and supply. The sartorius muscle is a long, slim, superficially running extensor of the thigh musculature. It originates from the anterior superior iliac spine of the pelvic bone and runs spirally towards the knee region. There it inserts at the pes anserinus medially from the tibial tuberosity. In its entire course the muscle is covered by a fascial duplication of the fascia lata. The innervation is supplied by the femoral nerve (L2-4).
