Light micrograph of endometrium, the inner lining of the uterus. There are endometrial glands, some of which are dilated (open white spaces) as a result of the inactivity or atrophy that follows menopause. Between the endometrial glands are dark blue stromal cells. Beneath the endometrium (lower part of image) is the myometrium (lighter blue or pink) or the smooth muscle wall of the uterus.
