The right and left levator ani lie almost horizontally in the<unk>  of the<unk> , separated by a narrow gap that transmits the urethra, vagina, and anal canal. The levator ani is usually considered in three parts: pubococcygeus, puborectalis, and iliococcygeus. The pubococcygeus, the main part of the levator, runs backward from the body of the pubis toward the coccyx and may be damaged during birth. Some fibers are inserted into the prostate, urethra, and vagina. The right and left puborectalis unite behind the anorectal junction to form a muscular sling. Some regard them as a part of the external anal sphincter. The iliococcygeus, the most posterior part of the levator ani, is often poorly developed. The coccygeus, situated behind the levator ani and frequently tendinous as much as muscular, extends from the ischial spine to the lateral margin of the sacrum and coccyx. The<unk>  cavity of the true<unk>  has the<unk>  as its inferior border (and the<unk>  brim as its superior border). The perineum has the<unk>  as its superior border. Some sources do not consider<unk> " and<unk>  diaphragm" to be identical, with the "diaphragm" consisting of only the levator ani and coccygeus, while the<unk> " also includes the perineal membrane and deep perineal pouch. However, other sources include the fascia as part of the diaphragm. In practice, the two terms are often used interchangeably. Posteriorly, the<unk>  extends into the anal triangle. The<unk>  has two hiatuses (gaps): Anteriorly urogenital hiatus through which urethra and vagina pass through and posteriorly rectal hiatus through which anal canal passes.
