The tibial nerve separates from the sciatic nerve at the lower third of the thigh, the cranial part of the popliteal fossa. It continues in the midline, posterior to the popliteal vessels. In the upper leg, it passes between the two heads of the gastrocnemius and then under the soleal arch. It supplies all the muscles of the calf and a cutaneous contribution to the sural (medial sural cutaneous) nerve. It then appears in the medial aspect of the ankle, where it gives off a calcaneal branch, enters the tarsal tunnel, and divides into medial and lateral plantar nerves. These enter their individual tunnels under the abductor hallucis and supply the intrinsic muscles of the foot and the skin of the sole of the foot.
