THE PROSTATE GLAND. 



THE Prostate Gland (7ipoiaTrjfj.i, to stand before) is a pale, firm, partly glandular 

 and partly muscular body, which is placed immediately below the neck of the 

 bladder and around the commencement of the urethra. It is placed in the pelvic 

 cavity, behind the lower part of the symphysis pubis, and above the deep layer of 

 the triangular ligament, and rests upon the rectum, through which it may be 

 distinctly felt, especially when enlarged. In shape and size it resembles a chestnut.

Its base is directed upward, and is situated immediately below the neck of the 

 bladder. 



Its apex is directed downward to the deep layer of the triangular ligament, 

 which it touches. 



Its posterior surface is flattened, marked by a slight longitudinal furrow, and 

 rests on the second part of the rectum, and is distant about one inch and a half 

 from the anus. 



Its anterior surface is convex, and placed about three-quarters of an inch 

 behind the pubic symphysis, from which it is separated by a plexus of veins and a 

 quantity of loose fat. It is connected to the pubic bone on either side by the 

 pubo-prostatic ligaments. 



The lateral surfaces are prominent, and are covered by the anterior portions
