sciatic nerve Posterior view of the right leg, showing the sciatic nerve and its branches.

The tibial nerve is a major nerve in the human body that branches from the sciatic nerve, typically above the knee. It is part of the peripheral nervous system, which relays sensory and motor impulses between the central nervous system and the rest of the body.12

The tibial nerve continues down the calf, innervating muscles such as the gastrocnemius, soleus, and tibialis posterior. It also supplies nerves to the deep muscles of the lower leg, as well as muscles in the ankle and the sole of the foot.2
