What is the nerve supply to the first web space of the foot?

The first web space of the foot is primarily innervated by the deep peroneal nerve. This nerve supplies sensations to the skin in that area, which is located between the first and second toes (the first web space). The deep peroneal nerve, also known as the deep fibular nerve, branches from the common peroneal nerve and plays a crucial role in both motor and sensory functions in the foot.

In addition to its sensory function, the deep peroneal nerve also innervates the muscles in the anterior compartment of the leg, including the tibialis anterior, which is essential for dorsiflexion of the foot. Thus, it is not only responsible for sensation but also influences the movement and position of the foot.

The other nerves listed do not supply the first web space. The superficial peroneal nerve primarily innervates the lateral compartment of the leg and provides sensation to the dorsum of the foot but not specifically to the first web space. The tibial nerve mainly innervates the muscles in the posterior compartment of the leg and the plantar aspect of the foot and does not contribute to the sensation in the web space. The medial plantar nerve, a branch of the tibial nerve, supplies the medial aspect
