462 SPLANCHNOLOGY, OR ANATOMY OF THE VISCERA 



peritoneum is reflected on to the bladder before reaching the 

 cervix. Its upper and back part is in contact with the small 

 intestine, its lower and front part with the bladder, the peri- 

 toneum separating them. The two folds of peritoneum after 

 investing the uterus are applied to each other, reaching across 

 to the lateral pelvic walls forming the broad ligaments. 



The uterus is 3 inches long, 2 wide, and 1 thick, and it weighs 

 about 1 ounce. It is divided into a body, fundus, and neck. 

 The fundus is the convex part above the entrance of the tubes; 

 the body is the part between this and the neck. In front of

the Fallopian tubes, at the upper part of the lateral borders* 

 the round ligaments are attached, and below and behind them 

 are the ligamenta ovarica. The cervix is the lower constricted, 

 rounded part, and around it is attached the vagina. At its 

 vaginal end is a round opening, the os uteri. 



The cavity of the uterus is small; that part within the body 

 is triangular, flattened anteroposteriorly, and presents at the 

 superior angles the openings of the Fallopian tubes; also, 

 at its junction with the neck it is constricted to form the os 

 internum or isthmus. The cavity of the cervix is barrel-shaped 

 and flattened anteroposteriorly, presenting on each wall a
