Medial sural cutaneous nerve

The medial sural cutaneous nerve (Latin: nervus cutaneus surae medialis) is a branch of the tibial nerve.

The medial sural cutaneous nerve arises at the upper region of the popliteal fossa, descends between the two heads of the gastrocnemius muscle and runs below the crural fascia. Further, the medial sural cutaneous nerve at the middle of the lower leg pierces the crural fascia and unites with the lateral sural cutaneous nerve to form the sural nerve.
