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.
External obturator muscle obturator membrane; the anterior branch of the obturator nerve reaches the thigh by passing in front of the muscle, and the posterior branch by piercing it. nononon In 33% of people a supernumerary muscle is found between the adductor brevis and minimus. While this muscle, when present, is similar to its neighbouring adductors, it is formed by separation from the superficial layer of the external obturator, and is thus not ontogenetically related to the adductor muscles of the hip. This muscle originates from the upper part of the inferior pubic ramus from where it runs downwards and laterally. In half
