ABDOMEN AND PELVIS 



543 



Bladder (Vesica urinaria). (Vide Fig. 292, and Spalteholz, Figs. 633, 



640.) 



Compare the form of the bladder in the two sexes; also its 

 position in the pelvis. Distend the bladder with air. How does 

 the naturally distended bladder compare in form with the 

 empty! Consult the pages on the male pelvis for the nomen- 

 clature of the bladder and the directions for dissection. 



Pelvic Part of Ureter (Pars pelvina ureteris). (Vide Fig. 291, and 

 Spalteholz, Fig. 665.) 



Isolate the ureter as it passes into the pelvis at the bifurca- 

 tion of the common iliac arteries. Compare the lengths of the 

 pelvic divisions in the male and female. Trace the ureter for- 

 ward to the base of the broad ligament. Establish its relations 

 to the uterine artery. What surgical significance has this ana- 

 tomical relation?

Diagram showing the relations of the ureter to the cervix [uteri] and adjacent vessels. The line 

 LL passes a little below the vaginal isthmus of the uterus. The longitudinal striations indicate the 

 vaginal wall, and the dotted line shows the contour of the cervix uteri. The vertical line, 25 mm., 

 indicates the length of the cervix uteri. (From Poirier et Charpy, Trait6 d'Anat. hum., Paris, 1901, t. v. 

 p. 457, Fig. 320.) 



Trace the ureter forward to the bladder and establish its 

 relation to the anterior vaginal wall. At what angle does the 

 ureter enter the bladder! 



Uterus (Uterus) (O. T. Womb). (Vide Spalteholz, Figs. 662, 664, 

 665, 667.) 



Use models and special preparations for this study. Estab- 

 lish the position and relations of the uterus. How does the 

 infantile compare with the adult organ? 



(a) Body of uterus (corpus uteri). 



(aa) Fundus of uterus (fundus uteri). 



(ab) Lateral margin (margo lateralis).
