Sural Nerve
*Descends in the groove between 2 heads of Gastrocnemius by short
saphenous nerve.
*In the lower 1/3 of the leg, it is joined by the Sural Communicating
branch of lateral popliteal nerve
*It runs behind & below the lateral malleolus then forward along the
lateral border of the foot.
*It supplies the skin of the lower 1/3 of the back of the leg & lateral border of the foot & little toe.
