WRIC PLEXUl 



989 



lesser and greater cavernous nerves, which arise from the forepart of the prostatic 

 plexus, and, after joining with branches from the pudendal nerve, pas? forward 

 beneath the pubic arch. 



The lesser cavernous nerves (nn. cavernosi penis minores; small cavernous nerves) 

 perforate the fibrous covering of the penis, near its root. 



The greater cavernous nerve (n. cavernosus penis major; large cavernous plexus) 

 passes forward along the dorsum of the penis, joins with the dorsal nerve of the 

 penis, and is distributed to the corpora cavernosa. 



The Vaginal Plexus arises from the lower part of the pelvic plexus. It is distributed 

 to the walls of the vagina, to the erectile tissue of the vestibule, and to the clitoris. 

 The nerves composing this plexus contain, like the vesical, a large proportion of 

 spinal nerve fibers. 



The Uterine Plexus accompanies the uterine artery to the side of the uterus, 

 between the layers of the broad ligament; it communicates with the ovarian plexus.
