SYMPATHETIC NERVE. 405 



The vesical plexus contains large offsets, with many white-fibred to the 

 or spinal nerves, and passes forwards to the side and neck of the 

 bladder. It gives one plexus to the vesicula seminalis, and another 

 to the vas deferens. 



The prostatic plexus leaves the front of the pelvic plexus, and to the pro- 

 supplies the substance of the prostate. At the front of the prostate 

 an offset (cavernous) is continued onwards to the dorsum of the 

 penis, to supply the cavernous structure. On the penis the 

 cavernous nerves join the pudic nerve. 



In the female there are the following additional plexuses for the offsets in 

 supply of the viscera peculiar to that sex : the female> 



Ovarian plttus. The chief nerves to the ovary are derived from to the 

 the renal and aortic plexuses, and accompany the ovarian artery ; ovary ; 

 but the uterine nerves supply some filaments to it. 



Vaginal nerves. The nerves of the vagina are large, and are not to the 

 plexiform, but consist in greater part of spinal nerve-fibres ; they vagina ; 

 end in the lower part of the tube. 



The uterine nerves are furnished to the uterus with only a small and to the 

 admixture of the spinal nerves ; they ascend along the side of the uterus - 

 uterus, and consist of long slender filaments without ganglia or 

 communications. The Fallopian tube receives its branches from 

 the uterine nerves. 



Some few nerves surrounding the arteries of the uterus are 

 plexiform and ganglionic. 



The LYMPHATIC GLANDS OF THE PELVIS form one chain in front Chain of pel- 



of the sacrum, and another along the internal iliac vessels : their "cg^nds; 

 efferent ducts join the lumbar glands. Into these glands run the 

 deep lymphatics of the penis, of the genital organs in the female, lymphatics 

 and the lymphatics of the viscera and wall of the pelvis. entering

ANATOMY OF THE VISCERA OF THE MALE PELVIS. 



DIRECTIONS. The rectum with the bladder and the bodies at 

 its base, viz., the vesiculse seminales, and the prostate gland, are 

 now to be taken bodily away for examination.
