 (upper inch). 



There is a ridge or raphe along the middle of the inner 

 surface of both the anterior and posterior walls. The walls 

 likewise present many transverse ridges or ruga. The lower 

 end of the vagina is embraced by the sphincter vaginae. 



THE UTERUS. 



The uterus or womb is a pear-shaped body, flattened from 

 before backwards, placed in the pelvis between the bladder 

 and rectum ; superiorly it does not reach above the brim of 

 the pelvis. The position corresponds to the pelvic axis. The 

 uterus is covered by peritoneum behind, above, and in front 

 except where it is attached to the base of the bladder ; the 

 peritoneum is reflected from off the sides to the pelvis, forming 

 the broad ligaments. The average length of the uterus is 3 inches, 

 breadth 2 inches, and thickness i inch, and it is, for the pur- 

 pose of description, divided into three parts : 



(1) The fundus is the broad upper end of the body, projecting 

 into the abdomen between the attachments of the Fallopian 

 tubes. 



(2) The body extends from the fundus to the neck, narrowing 

 as it approaches the latter ; at the junction of the fundus and 

 body is an angle to which the Fallopian tube is attached ; a 

 little anteriorly to this the round ligament is connected, below 

 and behind this the ovarian ligament is attached. 



(3) The neck or cervix uteri is surrounded below by the 

 vagina, into which it projects, forming a vaginal part, which 

 presents a transverse opening, the os uteri externum, bounded 

 by two thick lips, anterior and posterior, of which the anterior 

 is the thicker and the posterior the longer. The part pro- 

 jecting into the vagina is called the portio vaginalis. The 

 sulci in front of the anterior and behind the posterior lips are 

 the anterior and posterior fornices, of which the posterior is 

 much the deeper, and behind is in direct relation with 

 peritoneum (pouch of Douglas). 



The cavity of the uterus, flattened from before backwards, 

 is triangular in shape, the superior angles leading to tht.
