The deep peroneal nerve innervates which region?

• A. Lateral aspect of dorsum of foot
• B. Entire dorsum of foot
• C. Web space between the great toe and the second toe
• D. Web space between the third and fourth toes

Answer: (C)

The region the deep peroneal nerve supplies is the small area between the great toe and the second toe. This nerve travels with the muscles of the anterior leg and provides sensation specifically to that first interdigital web space, while the rest of the dorsum of the foot is served by the superficial peroneal nerve. So, the web space between the great toe and the second toe is the correct sensory territory for the deep peroneal nerve. The lateral aspect of the dorsum and the entire dorsum are mainly supplied by the superficial peroneal nerve, and the web space between the third and fourth toes is not the deep peroneal nerve’s area.
