278 Anatomy Applied to Medicine and Surgery. 



the vagina is in contact with the tissue that occupies the 

 lower part of the broad ligament, and has the vaginal 

 branch of the uterine artery with a venous plexus, on 

 either side, while the ureter crosses the upper part of the 

 lateral wall to reach the bladder, which lies in front of 

 the vagina. The lower end of the vagina pierces the tri- 

 angular ligament, and, hence, it is here that resistance to 

 dilatation is greatest. 



Bloodvessels of these Structures. The uterine artery 

 from the internal iliac passes horizontally through the 

 broad ligament towards the cervix uteri, and, when near 

 the latter, crosses the ureter, above which it lies, along with 

 its two accompanying veins. This artery gives branches to 

 the vagina, and, ascending in a tortuous manner about one- 

 twelfth or one-eighth of an inch from the uterus, furnishes 

 to the internal os a large artery, and terminates near the 

 cornu of the uterus by anastomosing with a branch of the 

 ovarian artery. The ovarian from the aorta enters the 

 broad ligament through the infundibulo-pelvic ligament, 

 i.e., the suspensory ligament of the ovary, and, after sup- 

 plying the ovary, it then enters the utero-ovarian ligament 

 and passes through its substance to reach the side of the 

 uterus, where it anastomoses with the uterine and the 

 funicular arteries. The funicular, a branch of the supe- 

 rior vesical, ascends along the round ligament to the 

 cornu uteri where it anastomoses with the uterine and the 

 ovarian. The ovarian veins empty as follows : Those on 

 the right side, into the vena cava at an acute angle, and 

 those on the left side, into the left renal vein at a right 

 angle. The lymphatics of the uterus and its appendages 

 form a network as delicate as the finest lace and terminate 

 as follows : Those from the body of the uterus pass up 

 along the suspensory ligament of the ovary to the lumbar 

 glands, or down the round ligament to the deep inguinal
