Sacral Plexus The inferior gluteal nerve (L5, S1, and S2) takes a similar route through the greater sciatic foramen, but inferior to piriformis. It travels superficial to the sciatic nerve and recurs to innervate gluteus maximus. The third branch to be formed purely from posterior rami is the nerve to piriformis (S1 and S2).

Facts and FAQs About Sciatica, Low Back and Leg Pain About the Sciatic Nerve in the Low Back. The sciatic nerve starts in your low back, which is called your lumbar spine. The nerve roots are at the L4 and L5 vertebrae (the 'L' means lumbar, and the numbers indicate the level of the vertebra—where it is in your back). The sciatic nerve also travels through your pelvic region (sacrum). In most people, the sciatic nerve runs under the piriformis muscle, which moves your thigh side to side. From there, the sciatic nerve descends through the buttocks and the back of the thighs. Behind your knee, smaller nerves branch out from the sciatic nerve and travel down to your feet. Your sciatic nerve is part of a complex structure: your body's nervous system. That system is responsible for transmitting pain and sensation to other parts of your body.
