Description
This diagram exemplifies the position of the arteries in the epithelial and muscular layers of the uterus. The arcuate artery lies at the base of the image base within the myometrium. It gives rise to the radial artery that also courses through the myometrium. When the radial artery leaves the myometrium it becomes the straight artery that terminates in the spiral arteries. The spiral arteries run in the stratum functionalis, the straight arteries run in the stratum basalis, while the radial arteries and the arcuate arteries run in the muscularis.
