Cutaneous branch of the obturator nerve Cutaneous branch of the obturator nerve Occasionally the communicating branch to the anterior cutaneous and saphenous branches of the femoral is continued down, as a cutaneous branch, to the thigh and leg, as the cutaneous branch of the obturator nerve. When this is so, it emerges from beneath the lower border of the Adductor longus, descends along the posterior margin of the sartorius to the medial side of the knee, where it pierces the deep fascia, communicates with the saphenous nerve, and is distributed to the skin of the tibial side of the leg as low down as its middle.
Posterior compartment of thigh Posterior compartment of thigh The posterior compartment of the thigh is one of the fascial compartments that contains the knee flexors and hip extensors known as the hamstring muscles, as well as vascular and nervous elements, particularly the sciatic nerve. The posterior compartment is a fascial compartment bounded by fascia. It is separated from the anterior compartment by two folds of deep fascia, known as the medial intermuscular septum and the lateral intermuscular septum. The muscles of the posterior compartment of the thigh are the: These muscles (or their tendons) apart from the short head of the biceps femoris, are
