402 PRACTICAL ANATOMY. 



about one-eighth inch in diameter, and passes up the 

 spermatic cord to the internal abdominal ring ; it then 

 descends into the pelvis, at the side of the bladder, to 

 its base, where it runs along the inner side of the semi- 

 nal vesicle ; here it becomes much enlarged and saccu- 

 lated ; it then becomes contracted, unites with the duct 

 of the seminal vesicle, and forms the ejaculatory duct, 

 which opens on the floor of the prostatic urethra, in front 

 of the veru montanum. 



THE SEMINAL VESICLES. 



The seminal vesicles are two tubular saculated struct- 

 ures which serve as reservoirs for the semen. They are 

 situated against the base of the bladder. Each sac is 

 about two and one-half inches long and one-third of an 

 inch in width. They consist of a single convoluted tube 

 having a series of pouches or alveoli. When uncoiled 

 each seminal vesicle is found to be a long tube about one- 

 twelfth of an inch in diameter and five inches long. It 

 terminates in a narrow duct, which joins the vas deferens 

 to form the ejaculatory duct, which is about an inch long 

 and opens in front of the veru montanum. The seminal 

 vesicles have an outer fibrous, a middle muscular, and 

 an internal mucous coat. The mucous membrane of the 

 vasa recta and epididymis is of the ciliated variety; 

 throughout the vas deferens and ejaculatory duct it is 

 of the columnar variety. 



THE FEMALE ORGANS OF GENERATION. 



The female organs of generation are divided into 

 external and internal. The external are the mons 

 veneris, the labia majora, the labia minora, the clitoris, 

 meatus urinarius, vaginal orifice, all comprised undei
