The saphenous nerve originates as a terminal sensory branch from which nerve?

• A. It is a terminal sensory branch from tibial nerve.
• B. It is a motor branch from the obturator nerve.
• C. It is a terminal sensory branch from femoral nerve.
• D. It is a mixed nerve from the sciatic nerve.

Answer: (C)

The saphenous nerve is a terminal sensory branch of the femoral nerve. The femoral nerve, arising from L2–L4, provides motor supply to the anterior thigh muscles and several sensory branches, with the saphenous nerve continuing distally through the adductor canal to supply skin along the medial leg and foot. It carries only sensory information and does not innervate muscles. It is not derived from the tibial, obturator, or sciatic trunks, which have different motor and sensory distributions.
