Which nerve is located outside the thigh?

• A. Common Peroneal Nerve
• B. Femoral Nerve
• C. Tibial Nerve
• D. Superficial Peroneal Nerve

Answer: (A)

The main idea is knowing where these nerves travel in relation to the thigh. The femoral nerve stays inside the thigh as it travels through the femoral triangle and supplies the anterior thigh muscles. The tibial and superficial peroneal nerves are in the leg region after the sciatic nerve splits, so they are not characteristically described as running outside the thigh. The common peroneal nerve, however, breaks away from the sciatic nerve and winds laterally around the head of the fibula, moving from the thigh region to the outside of the leg. That transition point—being along the outside of the knee and then into the leg—means it is located outside the thigh.
