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

Saphenous nerve

The saphenous nerve is the largest cutaneous branch of the femoral nerve.-Path:It approaches the femoral artery where this vessel passes beneath the sartorius, and lies in front of the artery, behind the aponeurotic covering of the adductor canal, as far as the opening in the lower part of the...
