The sural nerve receives sensation from the?

• A. lateral foot
• B. medial foot
• C. anterior foreleg
• D. dorsum of the foot

Answer: (A)

The sural nerve is primarily responsible for providing sensory innervation to the lateral aspect of the foot. Its origin is from the tibial nerve, which branches to provide sensations particularly to the skin on the posterior and lateral sides of the lower leg and foot. The specific area served by the sural nerve includes the lateral ankle and the lateral border of the foot, confirming that it is involved in sensation from that region. This anatomical function is significant in clinical assessments related to nerve health and injury. The other options, while they represent different regions of foot sensation, do not align with the function of the sural nerve. The medial foot is serviced by different nerves, including the medial plantar nerve, while the anterior foreleg is innervated primarily by the superficial peroneal nerve. The dorsum of the foot receives sensation primarily from the deep peroneal nerve and the superficial peroneal nerve, further distinguishing the sural nerve's role in sensation specifically to the lateral aspect.
