    mere cellular membrane, and is lost in tlie thin pelvic fascia over the front of the sacrum and pyriform muscle, where the vessels and nerves perforate it to reach the bladder. The outlet of the pelvis is closed in by the recto- vesical fasciae of opposite sides, which, like the levatores ani muscles, form a partition, concave above, convex below; this, however, is perforated by the rectum and prostate, both of which derive sheaths from the mem- brane in their passage through it. In the female, the recto-vesical fascia has the same arrangement, except that besides the rectum, the vagina, instead of the pros- tate, perforates and is ensheathed by it. By means of the ensheathing prolongations of this membrane, and the corresponding attachments of the subjacent levatores ani muscles, the pelvic viscera are slung in the cavity of the pelvis, with an easy mobility upwards and down- wards; as the musculo-membranous floor rises, or descends, these viscera are drawn upwards, or tend to pro- trude towards the outlet of the pelvis in the perineum. The relations of the bladder to surrounding parts are surgically very important (Fig. 1). The anterior surface of the bladder, entirely free of peritoneum, is situated behind the body and symphysis of the pubes, and the triangular ligament in the pubic arch. This latter relation of the bladder corresponds to the anterior half of the perineum, in front of the anus; or, in the female, to that smaller part of the vulva which extends between the clitoris and the orifice of the urethra. Above the pubes, the bladder, when distended, rises to the lower part of the abdominal wall.
