Anatomical terms of neuroanatomy [edit on Wikidata]

The anococcygeal nerve is a sensory nerve of the pelvis^[1] that arises from the coccygeal plexus.^[2] It pierces the coccygeus muscle and the sacrotuberous ligament to supply a small area of skin between the coccyx and anus,^[3] as well as the sacrococcygeal joint.^{[citation needed]} The number of anococcygeal nerves varies between one and three.^[4]
