TOPOGRAPHICAL ANATOMY OF THE 



anastomoses with the middle uterine artery, the vessel corresponding 

 to the external spermatic of the male. 



Dissection. — Remove the pelvic organs. Separate the vagina and 

 vestil)ide from the rectum, and make a longitudinal incision through the 

 dorsal wall of the whole reproductive canal. 



Interior of the uterus. — The soft mucous membrane of the 

 body and cornua of the uterus is raised into irregular and interrupted 



Rectum.

Yolds that become more prominent as the cervix is approached. At the 

 extreme end of each cornu there is a small firm papilla, on the summit 

 of which is the opening of the uterine tube (ostium uterinum tubre). 



The cervix of the uterus is readily distinguished by the greater 

 thickness of its wall and the narrowness of its lumen. The canal of 

 the cervix (canalis cervicis) is about 6 cm. in length, and communicates 

 with the cavity of the body of the uterus by the internal uterine open- 

 ing (orificium uteri internum). The vaginal end of the cervix projects 

 into the cavity of the vagina as a rounded prominence (portio vaginalis
