Identify the deep peroneal nerve in the anterior compartment of the leg. It is a branch of the common peroneal nerve. The deep peroneal nerve innervates the muscles of the anterior compartment. The deep peroneal nerve [two probes] continues onto the dorsum of the foot, where it gives motor branches to the extensor digitorum brevis muscle and extensor hallucis brevis muscle and ends as a cutaneous branch [probe] to the skin between the great toe and second toe.
