220 THE POCKET ANATOMY 



THE MALE ORGANS OF GENERATION. 



THE PROSTATE GLAND. 



The prostate gland adjoins the neck of the bladder and 

 surrounds the beginning of the urethra, which is placed 

 nearer the anterior than the posterior surface of the gland. 

 It is said to resemble a horse-chestnut in shape, with the 

 apex directed downwards. It measures about i^ inches 

 across its base and i^ inches in depth, and i inch from 

 before backwards, and is held in position by the anterior 

 true ligaments of the bladder. 



The prostate is perforated from base to apex by the urethra, 

 into which, as it lies in the gland, the common ejaeulatory 

 ducts open.

The prostate is surrounded by a sheath derived from the 

 recto-vesical fascia (vide p. 48) and by the prostatic plexus of 

 veins, and is supported by the levator ani. 



COWPER'S GLANDS. 



Cowper's glands are two small round bodies about the size 

 of a pea, placed behind the membranous part of the urethra, 

 between the two layers of the triangular ligament. Their 

 ducts are about I inch long, and pass forwards, piercing 

 anterior layer of triangular ligament, to open in the bulbous 

 part of the urethra. 



THE PENIS. 



The penis is divided into a root, body, and glans. 



The root is connected to the pubic rami by two strong pro- 

 cesses, the crura, and to the symphysis pubis by the sus- 

 pensory ligament. 



The glans forms the extremity ; at its summit is the opening
