ABDOMEN 



bladder may extend beyond the lateral border of the vagina, 

 and in such cases the relation of the ureter to the vagina 

 is much less intimate, 



Uterus. The uterus is the organ in which the im- 

 pregnated ovum is retained until the foetus is fully developed. 

 It lies in the middle part of the pelvis, resting upon the 

 posterior part of the upper surface of the bladder, and lying 

 beneath coils of small intestine. It is of modified piriform 

 shape, being flattened from before backwards. It measures 

 about three inches in length (75 mm.), and its long axis lies in 

 the axis of the inlet of the pelvis, and almost at right angles 

 with the long axis of the vagina (Fig. 244). Its breadth, at the

broadest part, is about two inches, and its greatest thickness 

 one inch. Its broad, upper end is directed upwards and 

 forwards, and is continuous at each side with an oviduct or 

 uterine tube. Its narrower, lower end is directed down- 

 wards and backwards, and passes through the upper part of 

 the vaginal wall into the cavity of the vagina. 



It is customary to describe the uterus as consisting of three 

 parts, viz. a fundus, a body, and a cervix. 



The fundus (fundus uteri) is that portion of the rounded 

 upper end which lies above a line drawn transversely across 

 the organ between the points where the uterine tubes enter. 

 It is completely covered by peritoneum.
