coccygeus

 [kok-sij´e-us]
pertaining to the coccyx.

coc·cyg·e·us mus·cle

[TA]
striated pelvic muscle associated with the deep (pelvic) aspect of the sacrospinous ligament, forming part of the pelvic diaphragm; origin, spine of ischium and sacrospinous ligament; insertion, sides of lower part of sacrum and upper part of coccyx; action, with the sacrospinous ligament assists in support of pelvic floor, theoretically increasingly so when intra-abdominal pressures increase; nerve supply, third and fourth sacral.

coccygeus

[koksij′ē·əs]
Etymology: Gk, kokkyx, cuckoo's beak
one of two muscles in the pelvic diaphragm. Stretching across the pelvic cavity like a hammock, it is a triangular sheet of muscle and tendinous fibers. It acts to draw the coccyx ventrally, helping to support the pelvic floor. Compare levator ani.

coccygeus

pertaining to the tail.
