The '''perineal nerve''' is a [[nerve]] arising from the [[pudendal nerve]] that supplies the [[perineum]].
==Structure==
The perineal nerve is the inferior and larger of the two terminal branches of the [[pudendal nerve]], is situated below the [[internal pudendal artery]].
It accompanies the [[perineal artery]] and divides into two branches:

* [[Deep branch of the perineal nerve]] (also known as "muscular")
