Lateral cutaneous nerve of thigh and then over the sartorius muscle into the thigh, where it divides into an anterior and a posterior branch. The anterior branch becomes superficial about 10 cm below the inguinal ligament, and divides into branches which are distributed to the skin of the anterior and lateral parts of the thigh, as far as the knee. The terminal filaments of this nerve frequently communicate with the anterior cutaneous branches of the femoral nerve, and with the infrapatellar branch of the saphenous nerve, forming with them the peripatellar plexus. The posterior branch pierces the fascia lata, and subdivides into filaments which pass
Posterior cutaneous nerve of thigh maximus with the inferior gluteal artery, and runs down the back of the thigh beneath the fascia lata, and over the long head of the biceps femoris to the back of the knee; here it pierces the deep fascia and accompanies the small saphenous vein to about the middle of the back of the leg, its terminal twigs communicating with the sural nerve. Its branches are all cutaneous, and are distributed to the gluteal region, the perineum, and the back of the thigh and leg. Posterior cutaneous nerve of thigh The posterior cutaneous nerve of the thigh (also called the
