coccygeus muscle in dogs

The Coccygeus is a muscle of the pelvic wall (i.e. peripheral to the pelvic floor), situated behind the levator ani and in front of 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. It assists the Levator ani and Piriformis in closing in the back part of the outlet of the pelvis. [WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

Where the coccygeus muscle is

It sits in the pelvis and trunk, within the muscular system. Only the region is known. The position shown is somewhere plausible inside it and nothing more.

What the coccygeus muscle connects to

The atlas records 3 typed relationships for it, across 2 kinds of connection. part of anatomical entity.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the coccygeus muscle. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called
