Tibial nerve

Tibial Nerve is a branch of the sciatic nerve. The tibial nerve passes through the popliteal fossa to pass below the arch of soleus.

Anatomy

The tibial nerve is the larger terminal branch of the sciatic nerve with root values of L4, L5, S1, S2, and S3. It originates in the popliteal fossa and extends to the foot to innervate muscles of the posterior compartment of the leg and sole of the foot.

Function

The tibial nerve provides motor and sensory innervation to the posterior compartment of the leg and the sole of the foot. It is responsible for plantar flexion and inversion of the foot, flexion of the toes, and sensation to the skin of the sole of the foot.

Clinical Significance

Damage to the tibial nerve can result in a condition known as tarsal tunnel syndrome. This condition is characterized by pain and numbness in the foot.
