Levator Ani Muscle - Definition

September 2017


Definition

The levator ani muscle is the primary pelvic floor muscle. It is responsible for aiding the pelvic floor in contraction during various bodily functions, such as orgasm.

The levator ani muscle has a shape reminiscent of a hammock; it is a thin muscle situated on either side of the pelvis. It is precisely located on the ischial spine and the pubis.

The levator ani consists of three portions: the puborectalis; the pubococcygeus muscle; and the iliococcygeus muscle. These three components work together to block the urogenital slot and act as sphincters for the anal canal and pelvic floor.
