The branches distributed to the pros- tate communicate with the corresponding vessel of the opposite side. The middle hemorrhoidal artery (a. haemorrhoidalis media) (Fig. 472) usually arises together with the preceding vessel. It is distributed to the rectum, anasto- mosing with the superior and inferior hemorrhoidal arteries. It gives branches to the seminal vesicle and prostate Vaginal arterie. Fig. 473.—The arteries of the internal organs of generatic of the female, seen from behind. (After Hyrtl.) The uterine artery {a. uterina) (Fig. 473) arises from the anterior division of the internal iliac and runs inward on the Levator ani to the neck of the uterus. About three-quarters of an inch from the cervix it crosses the front of the ureter, to which it supplies a small branch. Ascending in a tortuous course on the side of the uterus, between the layers of the broad ligament, it distributes branches to its substance and to the round ligament and the Fallopian tube (ramus tubarius), anastomosing near its termination with the ovarian artery. It gives a branch to the ovary (ramus ovarii), which anastomoses with a branch from the ovarian branches to the cen^ix of the uterus, cervicouterine, and a branch which descends on the vagina, the cervicovaginal, and, joining with branches from the vaginal arteries, form a median longitudinal vessel both in front and behind; these descend on the anterior and posterior surfaces of the vagina, and are named the azygos arteries of the vagina. The vaginal artery (a. vaginalis) usually
