Corpus: Medial sural cutaneous nerve

The cutaneus surae medialis nerve is a sensitive nerve branch from the tibial nerve.

The medial cutaneous nerve descends between the two heads of the gastrocnemius muscle and pierces its muscle fascia at the beginning of the distal half of the lower leg and then accompanies the saphenous vein. It joins with the ramus communicans peroneus of the lateral cutaneous nerve (from the common fibular nerve) to form the sural nerve.

The medial cutaneous nerve supplies the dorsal skin of the lower leg with sensation.
