THE GENERATIVE ORGANS. 

 MALE GENERATIVE ORGANS. 



WE shall confine our study of these organs to the 

 testicle, prostate gland, and parts of tJie penis. 



THE TESTICLE SPERMATOZOA. 



This is a tubular gland, whose chief specific secre- 

 tion is the spermatazoa ; it is enclosed by a firm, 

 dense connective-tissue capsule called the albu- 

 ginea, which sends inward several incomplete septa, 

 which divide the organ into a number of communi- 

 cating cavities, and unite at its posterior superior 

 part in a dense, wedge-shaped mass of connective 

 tissue, called the corpus Highmori. The more or 

 less conical cavities between the septa contain wind- 

 ing, anastomosing, and looped tubules, called semi- 

 nifcroiis tubules, which constitute the secreting por- 

 tion of the organ. As the tubules approach the 

 corpus Highmori, they become narrower and 

 straighter tubuli recti and are lined with cylindri- 

 cal epithelium, and, on entering that body, form a 

 net-like series of intercommunicating channels lined
