The levatores ani have such extensive origins and insertions thateach muscle is divided by Savage into two separate portions, pubo-and obturato-coceygeal.

Each levator arisesin front from the posterior aspect of the pubes near the symphysis(pubo-eoccygeus), behind, from the lower and inner surface of the 5 6 Attachment of the Muscular Floor of the Pelvis to the Bladder, Vagina, and Rectum (Savagel:B, bladder; V, vagina; 11, rectum; 1, pubo-eoccygeus; J, obturato-coccygeus; ?<. ischio-coceygeus; 4, ilio-pubic attachment of muscle: 5, coccygeal attachment; 6, median raphe:7, A reus tendineus of Luschka, aponeurotic fibres reflected to bladder. ischial spine, and between these origins from the white line thatrepresents the point of division of the pelvic fascia.
