pubococcygeus muscle

The pubococcygeus muscle or PC muscle is a hammock-like muscle, found in both sexes, that stretches from the pubic bone to the coccyx (tail bone) forming the floor of the pelvic cavity and supporting the pelvic organs. It is part of the levator ani group of muscles. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the pubococcygeus muscle is

The pubococcygeus muscle or PC muscle is a hammock-like muscle, found in both sexes, that stretches from the pubic bone to the coccyx (tail bone) forming the floor of the pelvic cavity and supporting the pelvic organs. It is part of the levator ani group of muscles. The atlas records it as a muscle at the organ scale in the human body.

Where the pubococcygeus muscle is

It sits in the pelvis and trunk, within the muscular system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the pubococcygeus muscle connects to

The atlas records 6 typed relationships for it, across 5 kinds of connection. part of levator ani muscle.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the pubococcygeus 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

Questions

Where is the pubococcygeus muscle?

It sits in the pelvis and trunk, within the muscular system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the pubococcygeus muscle connect to?

Part of: levator ani muscle.

Is the pubococcygeus muscle the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
