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

Structure[edit]

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.
