The remaining two muscles, the levator ani and the coccygeus, are ofespecial interest, since they largely supplement the fascia? in the formation ofthe septum, or pelvic diaphragm, which stretches across the bony canal andmaterially aids in supporting the vagina and the rectum and in the constitutionof the floor of the pelvis. The levator ani (Figs. 10, 11), the most important muscle of the pelvic dia-phragm, in general, with its fellow of the opposite side, presents the form of ahorseshoe, open in front, rather than that of a funnel, as very commonly true relations of this muscle have especially been emphasized by Luschka. Fig. 10.—Female pelvis, showing the form and attachments of the levatores ani muscles (Dickinson). and by Dickinson, whose descriptions are here utilized. These two muscles con-stitute a sling attached to the pubis in front, and, sweeping almost horizontallybackward, embrace the vagina and the rectum and become attached posteriorlyto the coccyx.
