Open the vas deferens by a short longitudinal incision about four inches above its termination, insert 

 the end of a small blowpipe, and inflate the lower portion of the vas deferens and the seminal vesicle; 

 they can then be readily exposed by careful dissection.

Open the bladder by a median vertical incision through the anterior wall, extending from 

 the summit to the base ; continue the incision along the median line of the urethra (divid-

 out the bladder and display its inner surface. 



Mucous membrane. 



Trigone. Plica ureterica. Uvula of Lieutaud. 

 Vessels : 



Arteries. Veins. Lymphatics. 

 Nerves.
