Which nerve is responsible for sensation in the dorsal foot?

The correct choice is the superficial peroneal nerve, which is primarily responsible for sensation on the dorsal aspect of the foot. The superficial peroneal nerve innervates the majority of the skin on the dorsum of the foot and the distal part of the leg. This nerve branches off the common peroneal nerve and becomes superficial as it travels down the leg, providing sensory input from areas including the top of the foot and the toes, excluding the area between the first and second toes, which is supplied by the deep peroneal nerve.

When evaluating the other nerves listed:

The deep peroneal nerve specifically provides sensory innervation to the area between the first and second toes and supplies motor innervation to muscles involved in dorsiflexion of the foot. The tibial nerve is primarily responsible for sensation on the plantar surface of the foot and does not play a role in dorsal foot sensation. The sural nerve does provide some sensation posterior and lateral to the leg and the lateral side of the foot, but it is not the main nerve responsible for dorsal foot sensation.
