20. 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.
