text: The<unk>  (long or internal<unk>  is the largest cutaneous branch of the femoral nerve.
  It approaches the femoral artery where this vessel passes beneath the Sartorius, and lies in front of it, behind the aponeurotic covering of the adductor canal, as far as the opening in the lower part of the Adductor magnus.
  Here it quits the artery, and emerges from behind the lower edge of the aponeurotic covering of the canal; it descends vertically along the medial side of the knee behind the Sartorius, pierces the fascia lata, between the tendons of the Sartorius and Gracilis, and becomes subcutaneous.
  The nerve then passes along the tibial side of the leg, accompanied by the great<unk>  vein, descends behind the medial border of the tibia, and, at the lower third of the leg, divides into two branches:
  one continues its course along the margin of the tibia, and ends at the ankle.
  the other passes in front of the ankle, and is distributed to the skin on the medial side of the foot, as far as the ball of the great toe, communicating with the medial branch of the superficial peroneal nerve.
