The sural nerve is a branch of which larger nerve?

Explanation:
The sural nerve is considered a branch associated with the tibial nerve because it is formed chiefly from a branch of the tibial nerve—the medial sural cutaneous nerve—with a small contributing connection from the common fibular (peroneal) nerve. This combined trunk runs down the posterior leg with the small saphenous vein and provides sensation to the posterolateral leg and lateral foot. Because the tibial component provides the major input that creates the sural nerve, anatomy references and NPTE-style questions typically classify it as stemming from the tibial nerve.
