sciatic nerve

a large peripheral nerve that connects the receptor and effector cells in the leg to the spinal cord. Pain in the leg, which may extend over the entire length of this nerve, from the buttocks to the foot, is called sciatica. The cause is most commonly a slipped disk pressing on the nerve root emerging from the spinal cord.
