The Sciatic Nerve The sciatic nerve innervates most of the hind limb. As is the case with many of the large nerves of the vertebrate nervous system, the sciatic nerve is a mixed-function nerve, meaning it is made up of the axons of sensory and motor neurons. The sciatic nerve gives rise to branches as it progresses distally along the hind limb.

Facts and FAQs About Sciatica, Low Back and Leg Pain The tibial nerves originate from the nerve roots at L4-5 and S1-3. The tibial nerves pass in front of the knee and downward into the foot (heel, sole, toes). If your sciatic nerve is compressed, it can cause pain along these pathways; that is how sciatic pain can spread or radiate to another part of your body. Popular Questions Asked and Answered

Sciatic nerve The sciatic nerve is the dominant nerve that innervates the lower back and the lower extremities. It travels from the lower spine, through the pelvis, and down each leg. It is the longest and widest nerve in the human body. The sciatic nerve primarily supplies the muscles of the lower leg, including the calf, ankle, and the back portion of the knee. It also supplies sensation to the sole of the foot, the ankle, the entire lower leg, and the back of the thigh. The sciatic nerve branches into different parts of the body along its path, hence its ability to supply such a large area of the body.
