Iliococcygeus

Looks like

The thin back part of the pelvic floor muscle (levator ani), from the side wall of the pelvis to the tailbone.

What it does

Supports the pelvic organs and lifts the pelvic floor.

Keeping it well

Weakened by childbirth and ageing; pelvic floor training helps leaks and heaviness. A bulge in the vagina needs assessment.
