The Coccygeus is a muscle of the pelvic floor, located posterior to levator ani and anterior to the sacrospinous ligament.

It is a triangular plane of muscular and tendinous fibers, arising by its apex from the spine of the ischium and sacrospinous ligament, and inserted by its base into the margin of the coccyx and into the side of the lowest piece of the sacrum.

In combination with the levator ani, it forms the pelvic diaphragm.

It assists the levator ani and piriformis in closing in the back part of the outlet of the pelvis.

Inferior Gluteal and Other Nerves Associated with Sacrospinous Ligament: A Cadaver Study.

American journal of obstetrics and gynecology.Am J Obstet Gynecol.2016 Jun 22. pii: S0002-9378(16)30368-4. doi: 10.1016/j.ajog.2016.06.025. [Epub ahead of print]
BACKGROUND: Reported rates of gluteal pain following sacrospinous ligament fixation range from 12-55% in the immediate postoperative period and from 4-15% 4-6 weeks postoperatively. The source of gluteal pain is often attributed to injury to the nerve to levator ani or pudendal nerve. The inferior g

The aim of this study was to explore the anatomical variations of the nerve to the levator ani (LA) and to relate these findings to LA dysfunction. One hundred fixed human female cadavers were dissected using transabdominal, gluteal, and perineal approaches, resulting in two hundred dissections of t

BACKGROUND: Vaginal delivery and aging are key risk factors for pelvic floor muscle dysfunction, which is a critical component of pelvic floor disorders. However, alterations in the pelvic floor muscle intrinsic structure that lead to muscle dysfunction because of childbirth and aging remain elusive
