The urinary bladder, Veslca urinarta, is the reservoir for the urine; 

 it is of oval form and lies behind the Sympliisis OK slum piibis, in front of the 

 rectum in the male, of the uterus in the female. Its summit. Vertex, is connec- 

 ted to the umbilius by means of the Lig amentum vesico-umbilicale medium (uraclms); 

 the body becomes enlarged posteriorly and inferiority into the base or Ftindus 

 vesicae; the sides are connected to the umbilicus by means of the Lig amenta 

 vesico-umbilicalia later alia (obliterated hypogastric arteries). The bladder has 

 the following layers: peritoneum at the summit, the posterior wall and the 

 sides; muscular layer composed of longitudinal and transverse fibres (Detrusor 

 urinae) and of circular fibres (Sphincter vesicae); sub mucous connective 

 tissue and finally the mucous membrane covered with stratefied epithelium. 



The ureters pass obliquely downwards and inwards, enter the coats of 

 the bladder, and open into the fundns of the bladder by two narrow and oblique 

 slit-like openings ; at the line of union of these with the urethra is the trigone, 

 Trigonum Lieutaudii; the summit of this triangle is called Uvula vesicae (see 

 Fig. 403); here the muscular layer of the bladder is more strongly developed.
