rectum in the male, forming the recto-vesical or recto-genital pouch ; in the female 

 a slit-like peritoneal depression, called the utero-vesical pouch, intervenes between 

 the anterior surface of the' uterus and the bladder (Fig. 996). The inferior part of 

 the bladder lies below the peritoneum, and is for the most' part directed towards 

 the pelvic floor. In the median plane it is supported by the symphysis pubis and the 

 retro-pubic pad of fat ; farther back in the male it rests upon the prostate and on 

 the lower part of the rectum, from the latter of which it is separated by the vesiculse 

 seminales and the terminal parts of the ductus deferentes. In the female it rests

 The urinary bladder and rectum are both greatly distended. 



upon the anterior wall of the vagina. Laterally the bladder is supported by the 

 levatores ani muscles, and farther from the median plane it rests on each side on 

 the obturator internus ; it is separated from the layer of the pelvic fascia covering 

 these muscles by loose areolar tissue. 



The opening of the urethra, orificium urethrae internum or internal urethral 



' orifice, is placed in, or near, the part of the bladder wall which lies lowest in 



the pelvic cavity. The term neck, or cervix, is often applied to this region, the
