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 ventral ramus 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.
