Which nerve is located at the top back of the calf?

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

Answer: (C)

The main idea is tracing where the major nerves run in the lower leg. The tibial nerve travels through the posterior part of the leg, starting in the popliteal fossa right behind the knee and continuing down the back of the calf. That makes it the nerve you’d feel at the top back of the calf region. It supplies the muscles in the posterior leg, like the gastrocnemius and soleus, and then moves into the foot as the plantar nerves. In contrast, the femoral nerve is mainly in the front of the thigh, not the calf. The common peroneal nerve wraps around the outer knee near the fibular head and then descends along the front and lateral sides of the leg. The superficial peroneal nerve runs in the lateral compartment of the leg and does not lie at the back of the calf.
