PELVIS.

The pelvis is a cavity below the abdomen, and under the
pubes, containing the urinary bladder, rectum, and organs
of generation.

VESICA URINARIA.

The urinary bladder is a membranous sac in the pelvis
■without the peritoneum, which in part gives it a coat, or
tunic. It is situated, in men, between the pubes and rec-
tum ; in women, between the pubes and uterus, being fixed
at its anterior and inferior part, to the arch of the pubes, by
its neck,-and the urethra.

Division. Anatomists divide the urinary bladder into a
fundus, which is loose in the abdomen, and, when the blad-
der is distended, reaches the navel, and even the stomach ;
a neck, before which the prostate gland h placed in men;
and a body, or that part composing the chief bulk t/f the
gladder, distinguished by an anterior and posterior part and
shies.

The anterior half of this dilutable base is connected infe-
riorly, in man, to the rectum, aud in women, to the uterus ;
its middle, part to the bones of the pelvis, by means of cellu-
lar membrane and muscular fibres; and its superior part is
attached loosely to the muscles of.the abdomen. There is
also a round ligament, which proceeds from the middle of the
fundus of the bladder, between the peritoneum and linea
alba, to the umbilicus, which is called the uraefpus,
, Structure. It is composed of three membranes, like the
intestines, one peritoneal, a muscular coat, and a villous.
