Anococcygeal nerve explained

Anococcygeal nerve
Latin:	nervus anococcygeus
Branchfrom:	Coccygeal plexus

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