EXCRETORY AND REPRODUCTIVE SYSTEMS. 167 
corpus spongiosum to the point of the penis. The ureter, 
bladder, and urethra consist largely of muscular tissue, the 
lining being formed by mucous membrane. 
THE FEMALE REPRODUCTIVE SYSTEM. 
The female reproductive organs are the two ovaries, a 
pair of Fallopian tubes, a uterus, and a vagina. To 
demonstrate these, the entire ventral abdominal wall must 
be removed and the pubic symphysis severed with the bone- 
cutters. The ovaries are the small yellowish oval bodies 
about one centimeter long lying just caudad of the kidneys, 
against the dorsal abdominal wall. From the vicinity of 
each extends a tube caudad to join its fellow in the median 
line ventrad to the rectum (Figs. 55 and 86). The cranial 
portions of these are the Fallopian tubes, and the larger 
caudal portions are the cornua of the uterus. The junc- 
tion of the cornua in the median line forms the body of the 
uterus. 
The Fallopian tube is smaller in diameter than the cornu 
of the uterus, generally more or less contorted, and termi- 
nates by a fimbriated expansion or mouth opening freely 
into the abdominal cavity. 
The Fallopian tubes and uterus are suspended by the 
broad ligament, or ligamentum latum, which is a fold of 
the peritoneum attached to the dorsal abdominal wall. The 
round ligament, or ligamentum rotundum, also aids in 
keeping the uterus in place. This appears as a thickening 
of the broad ligament when the latter is looked through 
toward the light. The round ligament extends from about 
the middle of the horn or cornu of the uterus ventrad of 
Poupart’s ligament, and through the muscles of the ab- 
dominal wall beneath the skin of the inguinal region, where 
it gradually loses itself. It is exceedingly delicate and 
thread-like.
