Anococcygeal nerve
nerve in the pelvis

The anococcygeal nerve is a sensory nerve of the pelvis 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, as well as the sacrococcygeal joint. The number of anococcygeal nerves varies between one and three.
This brief starts where responsible research should: with the source description of “Anococcygeal nerve” as nerve in the pelvis. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as nerve in the pelvis. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 22, 2026. The linked authority identifier is Q1134638. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
