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.
