Hi there,

How well do you know your sciatic nerve?

It is often thought of as a single nerve, but it is actually made up of two separate branches sheathed together by connective tissue in their early travels. They separate in the lower thigh, higher or lower in different people.

The two nerves are the TIBIAL and the COMMON PERONEAL.

The tibial part is responsible for innervating the hamstrings and posterior thigh, the posterior leg (remember this means the lower leg!) and the plantar surface of the foot.

The common peroneal serves the muscles of the lateral and anterior leg, and the dorsum of the foot.

Think about which muscles these include...
