Three distinct muscles form the levator ani: puborectalis, pubococcygeus, and iliococcygeus. Together they create the pelvic diaphragm that supports pelvic organs and aids in continence. Puborectalis loops around the anorectal junction to form a sling, which helps maintain anorectal angle and continence. Pubococcygeus and iliococcygeus extend from the pubic bone and pelvic fascia to the coccyx and midline structures, reinforcing the pelvic floor. Some texts describe the levator ani as a single muscular sheet because the fibers blend, but anatomically it is counted as three separate muscles. That’s why the correct count is three.
