DESCRIPTION
Levator ani is a broad flat muscle that forms most of the pelvic floor.
ORIGIN
The pubo-coccygeal part of the levator ani originates from the back of the body of the pubis and passes almost horizontally.

The pubo-rectal part of levator ani originates with the pubo-coccygeal part, but passes below it.
The ilio-coccygeal part of levator ani originates from obturator fascia between the obturator canal and the ischial spine.
