==Muscles==
S2 supplies many muscles, either directly or through nerves originating from S2. They are not innervated with S2 as single origin, but partly by S2 and partly by other spinal nerves. They are most commonly known to govern the toes. The muscles are:
* sphincter urethrae membranaceae
* gluteus maximus muscle
* piriformis
* obturator internus muscle
* superior gemellus
* semitendinosus
* gastrocnemius
* flexor hallucis longus
* abductor digiti minimi
* quadratus plantae
