What does the sural communicating nerve do?
When there is no communication between medial sural cutaneous nerve and peroneal communicating nerve, the medial sural cutaneous nerve supplies the lateral surface of the leg and gives off lateral branch to the heel and continues as lateral dorsal cutaneous nerve.
What does the common peroneal nerve supply?
The superficial fibular (peroneal) nerve supplies the muscles of the lateral compartment of the leg and provides sensation to the anterolateral aspect of the leg. The deep fibular (peroneal) nerve, on the other hand, mainly supplies the muscles of the anterior compartment of the leg and the dorsum of the foot.
