Pelvic floor

Uncommon card · No. 109101

The pelvic floor or pelvic diaphragm is a tapered muscular diaphragm, that limits the bottom of the pelvis. It extends from the pubic bone at the front to the coccyx at the back, stretching laterally between the two ischial spines along a thickened connective tissue band called the arcus tendineus. It consists primarily of the levator ani muscle group (which includes the puborectalis, pubococcygeus, and iliococcygeus) together with the coccygeus muscle and covering fascia. Functionally, the pelvic floor maintains baseline muscle tone to anchor and prevent prolapse of the pelvic viscera; including the bladder, uterus, and rectum; against intra-abdominal pressure, supports urinary and fecal continence, and relaxes during micturition, defecation, sexual function, and parturition.
