The coccygeal nerve is the spinal nerve that corresponds to the coccyx bone.


The coccygeal nerve is the 31st spinal nerve. It arises from the sacral plexus, and its anterior root helps form the coccygeal plexus. It does not divide into a medial and lateral branch. It is distributed to the skin over the back of the coccyx.
