The uterine artery arises from the anterior division of the internal iliac artery just below or in common with the vaginal artery. It passes downward and medially on the levator ani toward the cervix. It crosses in front of the ureter one to one and a half centimeters from the cervix. It then turns upward and ascends in a twisted course between the layers of the broad ligament and on the side of the uterus. It sends numerous branches at a right angle to spread over both surfaces of the uterus in a winding way. It anastomoses with the uterine branch of the ovarian artery. The cervical branch of the uterine artery springs from that vessel as it crosses the ureter. It passes directly medially and divides into four or five branches. Some of these branches anastomose with branches of the vaginal to form the vaginal arteries. They run along the median line of the vaginal wall, one lying in front and the other behind.
