Description[edit | edit source]
Coccygeus also known as ischiococcygeus is a triangular-shaped sheet of muscle located posterior to the levator ani muscles and anterior to the sacrospinous ligament in the pelvic floor. The coccygeus, together with the levator ani, forms the pelvic diaphragm.
Origin[edit | edit source]
It originates from the ischial spine.
Insertion[edit | edit source]
The lateral aspect of the coccyx and the sacrum, along the sacrospinous ligament.[1]
Nerve[edit | edit source]
The anterior rami of S4 an S5.
Artery[edit | edit source]
Internal pudendal and inferior gluteal artery.
Function[edit | edit source]
- It supports the pelvic viscera.
- It flexes the coccyx.
- It weakly aids the puborectalis to control urination an defecation especially when there is an increase in intra-abdominal pressure.
Clinical relevance[edit | edit source]
The pelvic floor muscles (PFM), which consist of the levator ani and coccygeus muscles, are crucial for supporting pelvic organs.
Assessment[edit | edit source]
