LYMPHATICS OF VAGINA 



745 



The lymphatics of the clitoris. — The lymphatics of the glans of the clitoris 

 form an abundant network from which collecting vessels pass toward the symphy- 

 sis pubis, and thence principally to the deeper inguinal nodes, one or two, however, 

 passing through the inguinal canal to terminate in the lower external iliac nodes. 



The lymphatics of the ovary. — The ovary has a remarkably rich lymphatic 

 plexus, from which from four to six vessels leave the hilus and follow the ovarian 

 arterj' to the lumbar nodes. One vessel may run in the broad ligament to the 

 internal iliac group. 



The lymphatics of the Fallopian tube form three capillary networks from 

 which collecting vessels run in part with those of the ovary, and in part with the 

 uterine lymph-vessels. 



The lymphatics of the uterus. — -According to Poirier, the lymphatics of the 

 uterus arise from three capillary plexuses, a mucous, a muscular, and a peritoneal. 

 The collecting vessels from the body of the uterus are in three sets: — (1) Those 

 from the fundus, consisting of four or five vessels, run lateralward in the suspen-

sory ligament of the ovary and follow the ovarian vessels to the lumbar and pre- 

 aortic nodes. They anastomose with the lymphatics from the ovary opposite the 

 fifth lumbar vertebra; (2) some small vessels from the fundus follow the round 

 ligament of the uterus and terminate in the inguinal nodes; and (3) others from the 

 body of the uterus pass laterally with the uterine vessels and terminate in the iliac 

 nodes. 



The collecting vessels from the cervix, five to eight in number, form a large 

 lymphatic plexus just after leaving the cervix. From this plexus run three sets of 

 vessels. Two or three vessels pass lateralward with the uterine artery in front of 

 the ureter, and end in the external iliac nodes; a second set passes behind the 

 ureter and ends in a node of the hypogastric group, and a third set from the 

 posterior surface runs downward over the vagina and then backward and upward 

 to end in the lateral sacral nodes and node of the promontory of the sacrum. 



The lymphatics of the vagina (fig. 590). — There are two lymphatic plexuses in 

 the vagina, a superficial and deep — the latter, the mucosal plexus, being ex- 

 ceedingly rich. The collecting vessels are in three groups. The superior set 

 drains the upper third of the vagina and takes the same course as those from the 

 lower cervical portion of the uterus; the middle set follows the vaginal artery to
