Lower down, the anterior wall in the median plane is intimately connected with the urethra (Fig. 1033). Near the median plane, the posterior wall in its upper portion is covered for a distance of about a quarter of an inch by the peritoneum, which here forms the anterior boundary of the deepest part of the recto-uterine pouch. The depth to which the peritoneum of this pouch descends practically corresponds to the level of the spina ischiadica. Lower down, the posterior wall lies close against the rectum, from which it is separated by a layer of the pelvic fascia. As, however, the orifice of the vagina is approached^ the rectum and vagina become separated by a considerable interval, which is occupied by^a mass of fibrous and fatty tissue, often called the " perineum " or " perineal ; At the sides the vagina is supported by the levatores ani muscles. The terminal part of the ureter lies not far from the lateral wall of the upper part of the vagina, as it passes from above and beh
