The sciatic nerve innervates multiple muscles and skin cells in the lower extremities Branches and supply. The sacral plexus provides a large number of branches which can be divided into posterior, anterior and terminal branches. The posterior branches are derived from posterior divisions of the anterior rami of spinal nerves, while the anterior branches are derived from the anterior divisions.The largest and only terminal branch is the sciatic nerve that provides two divisions.

The sciatic nerve branches, just proximal to the popliteal fossa, giving rise to the common fibular (peroneal) and tibial nerves. The common fibular nerve provides sensory innervation to the posterolateral lower leg and dorsum of the foot. The common fibular nerve branches into the deep fibular and superficial fibular nerves The sciatic nerve is located in the back of the leg. It supplies the muscles of the back of the knee and lower leg. The sciatic nerve also provides sensation to the back of the thigh, part of the lower leg, and the sole of the foot. Partial damage to the nerve may demonstrate weakness of knee flexion (bending), weakness of foot movements.

For the majority of people, sciatic nerve pain is caused by a herniated disc in the back, which means a disc in the spine develops a slight crack or tear The main nerve traveling down the leg is the sciatic nerve. Pain associated with the sciatic nerve usually originates higher along the spinal cord when nerve roots become compressed or damaged from narrowing of the vertebral column or from a slipped disk. Symptoms can include tingling, numbness, or pain, which radiates to the buttocks legs and. The sciatic nerve is the largest nerve in the body. There are two sciatic nerves, one on each side of the body.

Pinched Sciatic Nerve: Causes & Risk Factors. Most of the time, a sciatic nerve becomes compressed by one of three anatomical events: Herniated Disc: The discs in our spine consist of a hard outer shell that encases a softer, gel-like substance. Over time, this outer shell may break down, causing the inner filling to spurt out and press on.
The motor distribution of the sciatic nerve is as follows Thigh tibial division (posterior compartment of the thigh) long head of biceps femoris semimembranosus semitendinosus peroneal division (superficial and lateral to tibial division). The sciatic nerve arises from the ventral rami of L4-S3 and is composed of Tibial and common peroneal nerve components. These fibers provide coverage to the distal femur, knee, leg, ankle, and foot (expected of the medial aspect of the leg and foot).
