656 THE PENIS. 



tuting a strong fascia, which invests the sides and infe- 

 rior surface of this gland, thus forming for it a capsule. 

 Its density is firm and resisting. Its color is of a grayish 

 hue. The posterior surface is flat and notched, which 

 divides it into two lateral lohes, and on raising the vesicu- 

 las seminales, a transverse process is ohserved connecting 

 the lateral lobes, called hy Sir Everard Home the third 

 or middle lobe of the prostate. The sides of the prostate 

 are round, smooth, and covered by the levatores ani mus- 

 cles, veins, and a strong fascia. The structure of this gland 

 consists of mucous follicles, which discharge by ten or 

 more excretory ducts into the urethra on either side of the 

 caput gallinaginis, and these follicles are surrounded by a 

 condensed fibrous or cellular tissue. The fluid of this 

 gland is white or brownish, and viscid. 



THE PENIS. 



The penis is connected to the symphysis pubis, and in 

 front of it. It is divided into a root, body, and extremity. 

 The root is attached by two crura to the rami of the is- 

 chium and pubis. The body forms the intermediate or cen- 

 tral portion, while the extremity consists of the glans penis. 



Structure. The penis consists of integument, cellular 

 tissue, the corpora cavernosa, corpus spongiosum, and ure- 

 thra. 



The integument is delicate, thin, loose, and free from 

 fat. It projects beyond the extremity of the glans, so as to 

 form a loose sheath termed the prepuce. It is then re- 

 flected back to the root of the glans, thence over the glans 

 itself, where it is very delicate, and is traced to the open- 

 ing of the urethra continuous with the lining membrane 

 of this canal. The prepuce is connected to the glans by a 

 longitudinal fold or process called frenum preputii. Its in- 

 ner layer is mucous and is connected to the outer by loose 

 cellular tissue, which readily allows the infiltration of se- 

 rum. Around the corona of the glans, and beneath the 

 skin, numerous sebaceous glands are seen, called glandulce 

 odoriferce or glands of Tyson.
