FEMALE ORGANS OF GENERATION 227 



Fallopian tubes. Where the body joins the neck there is a 

 constriction, the os uteri internum. 



The ligaments are two anterior or utero-vesical, two pos- 

 terior or recto- vaginal, and two lateral or broad ligaments, all 

 formed of peritoneum. 



The broad ligaments are formed of a double layer of peri- 

 toneum passing from the lateral margins of the uterus to the 

 sides of the pelvis. Between the two layers of this ligament 

 on each side are the Fallopian tube, the round ligament, the 

 parovarium, the ovary and its ligament, uterine and ovarian 

 vessels, nerves and lymphatics. 



The round ligament is a cord placed between the layers of 

 the broad ligament, extending from the superior angle of the 

 uterus to the internal abdominal ring ; thence it passes into 

 the inguinal canal to lose itself in the labium. It is enclosed 

 for some part of the way in peritoneum, which is known as 

 the canal of Nuck. 



THE APPENDAGES OF THE UTERUS. 



The Fallopian tubes are two in number, placed in the 

 upper margin of the broad ligament. Each tube measures 

 about 4 inches in length. The cavity commences by a narrow 

 orifice called the ostium internum, and terminates in a fimbriated 

 extremity, which passes over the superior and posterior borders 

 of the ovary, and is attached by the fimbria ovarica to the 

 superior pole of the ovary. 



The ovaries are two in number, and correspond to the testes 

 in the male ; they are of a flattened ovoid form, vertically 

 placed in the posterior part of the broad ligament. By its 

 anterior border the ovary is connected to the broad ligament, 

 and by its lower pole to the uterus by a proper ligament, 

 extending to the superior angle of the uterus, and called the 

 ligament of the ovary. The lateral surfaces and posterior 

 border are free. The superior pole and posterior border are 

 embraced by the Fallopian tube ; on its inner surface it is in 

 relation with small intestine in Douglas' pouch, and exter- 

 nally lies in a peritoneal fossa between the external and internal 

 iliac vessels as they diverge. The vessels enter the hilum at 

 the attached anterior border. 



The parovarium lies between the Fallopian tube and ovary, 

 and is the remains of the Wolffian body.
