The deep peroneal nerve is the nerve of the anterior compament of the leg and the dorsum of the foot. It is a terminal branch of common peroneal nerve. Its muscular branches are1. Muscles of the anterior compament of the leg; These include: (i) Tibialis anterior, (ii) Extensor hallucis longus. (iii) Extensor digitorum longus, and (iv) Peroneus Teius.2. The extensor digitorum brevis (on the dorsum of the foot), is supplied by the lateral terminal branch of the deep peroneal nerveParalysis of muscles of the anterior compament of the leg results in loss of the power of dorsiflexion of the foot. As a result, the foot is plantar flexed. The condition is called as "foot drop".Reference: Chaurasia Volume II; 7th edition; Page no: 105
