Tibial nerve

The tibial nerve is one of two terminal branches of the sciatic nerve and supplies the leg and foot with motor and sensory supply.


Gross anatomy


Fibers arise from the L4 to S3 nerve roots and form one of two parts of the sciatic nerve. It forms its own discrete nerve after the terminal division of the sciatic nerve, usually in the lower third of the thigh.


Passes straight down through the popliteal fossa, posterior to the popliteal vessels, to pass inferiorly between the heads of gastrocnemius and deep to the soleus muscle. Emerges to pass under the flexor retinaculum in the tarsal tunnel, enclosed in a synovial sheath containing the posterior tibial vessels. At the level of the medial malleolus it divides into three terminal branches: medial and lateral plantar nerves, and the medial calcaneal nerve.
