SUKGICAL ANATOMY OF THE PENIS AND 

 MALE UKETHHA. 



The integument of the penis consists externally, of 

 very lax, loose skin, destitute of fat, which at the corona 

 glandis is reflected over the glans, and has an internal 

 mucous surface continuous with that of the glans ; imme- 

 diately below the meatus urinarius this membrane is 

 gathered into a fold, the frcenum preputii. Behind the 

 corona, and in the sulcus, are a number of glands which 

 secrete the smegma. Beneath the skin is a layer of loose 

 muscular fibres, analogous to the dartos, arranged circu- 

 larly and lying in loose cellular tissue. Beneath this is 

 a tough, elastic fascia, enveloping the entire body of the 

 organ, sending in a process beneath the urethra and 

 corpora cavernosa, continuous with the superficial fascia 

 of the perineum, incorporated at its root with the suspen- 

 sory ligament; between the two laminae of which lie the 

 dorsal vessels and nerves. The upper portion of the 

 body of the penis is composed of the corpora cavernosa, 

 which, arising from the inner aspect of the horizontal 

 rami of the pubes, unite along the mesial line, this union 

 being marked by a septum, called the septum peetini- 

 forme, which, however, is wanting in front. The cor- 

 pora cavernosa terminate in the front, by a rounded mar- 

 gin, which projects into the base of the glans. The 

 inferior portion of the body of the glans is formed by the 

 corpus spongiosum, containing the urethra. It com-
