ABDOMEN 



deep vein and note that, at the symphysis, it passes backwards, 

 between the two laminae of the suspensory ligament, to join the 

 pudendal plexus. Between the laminae of the suspensory liga- 

 ment on each side of the deep dorsal vein find the dorsal arteries 

 and nerves of the penis and trace them forwards towards the 

 glans.

the Penis. The suspensory 

 ligament of the penis is a 

 strong nbro-elastic band of 

 a triangular shape. By its 

 posterior border it is at- 

 tached to the symphysis 

 pubis. Towards the penis 

 it separates into a right and 

 a left lamella, which join 

 the deep fascia of the body 

 of the organ. Between the 

 two lamellae are placed the 

 dorsal vessels and nerves 

 (Figs. 92, 1 06). 



Dorsal Vessels and 

 Nerves. In the median line 

 of the dorsum of the penis, 

 in the superficial fascia, lies 

 the superficial dorsal vein, 

 and, under cover of the deep 

 fascia, in the groove which 

 extends along the middle 

 line of the dorsum of the

showing the main Blood - Vessels lateral to the deep dorsal 



vein are the right and left 



dorsal arteries and lateral to the arteries are the dorsal nerves. ' 

 On the dorsum of the penis, therefore, there are two veins, 

 superficial and deep ; two arteries ; and two nerves. 



The superficial dorsal vein receives tributaries from the 

 prepuce and terminates posteriorly in the superficial external 

 pudendal veins. 



The deep dorsal vein of the penis begins by the union of 

 several twigs from the glans and prepuce. It extends back- 

 wards in the middle line, passes between the two layers of
