View the levator ani in 3DOrigin
Body of the pubis, tendinous arch of the levator ani, and ischial spine.
Insertion
Perineal body, coccyx, anococcygeal ligament and the contralateral muscle — forming the pelvic diaphragm's sling.
Action
Supports the pelvic organs, maintains continence, and forms the voluntary sphincter mechanism of the anorectum with the puborectalis.
Nerve supply
Pudendal nerve (S2–S4) and direct sacral branches.
Blood supply
Inferior gluteal and pudendal arteries.
Clinical relevance
Vaginal childbirth stretches it — the muscle behind pelvic organ prolapse and stress incontinence; puborectalis release treats obstructed defecation.
