Pudendal Nerve

The pudendal nerve is a sensory and somatic nerve in the pelvic region that innervates the external genitalia of both sexes, as well as sphincters for the bladder and the rectum. It originates in Onuf's nucleus in the sacral region of the spinal cord, and travels in the S2-S4 nerves of the sacral plexus.
