The uterus has four main parts. The fundus is the upper part of the uterus. It has a rounded shape. Another part of the uterus is the body. The uterotubal angles are the parts connected to the Fallopian tubes. The bottom part of the uterus is the cervix. The uterus has three layers. The outer layer is called the perimetrium. It is a thin layer that surrounds the outside of the uterus. The perimetrium is made of tissue made of epithelial cells. The middle layer is the myometrium. Most of the uterus is made up of the myometrium. The layer on the inside is the endometrium. The endometrium is made of secretory, ciliated, and basal cells. The uterus is not in the same place for all women. It is tilted forward in most women. Other women have a uterus that tilts up or backwards.
