Question #43

Which of the following statements is correct?

The sciatic nerve gives off two branches, the tibial and common peroneal nerves. Below the popliteal fossa the tibial nerve divides to form the sural nerve. This runs with the short saphenous vein, supplies skin over the lateral foot and calf, and can be harvested for nerve transplant.

The common peroneal nerve wraps around the head of the fibula (where it can often be damaged) and divides into the deep and superficial peroneal nerves.

The superficial peroneal nerve supplies the lateral compartment muscles and skin over the dorsum of the foot and lateral aspect of the leg.

The saphenous nerve is formed from the posterior division of the femoral nerve in the thigh. It runs with the long saphenous vein and supplies skin over the medial foot and leg.
