The lining of the uterus during pregnancy.
A membrane which lines the uterus after fertilisation.
Epithelial tissue of the endometrium, the lining of the uterus, that is shed in menstruation and after the birth of a baby.
The modified mucous membrane that lines the wall of the uterus (womb) during pregnancy and is shed with the afterbirth at parturition. There are three regions: the decidua capsularis, a thin layer that covers the embryo; the decidua basalis, where the embryo is attached; and the decidua parietalis, which is not in contact with the embryo.
The soft coat which lines the interior of the womb during pregnancy and which is cast off at birth.
The endometrium or lining of the uterus and the tissue around the ectopically located fertilized ovum, e.g., in the fallopian tube or peritoneal cavity. The decidua has an interior compact layer and a surface spongy layer. The vasculature, glands, and interstitial cells of the endometrium undergo marked hypertrophy during pregnancy.
The uterine lining, known as the decidua, develops and thickens during pregnancy. However, during childbirth, the superficial layers of the decidua are shed from the body.
The inner lining of the uterus, where a fertilized egg attaches to grow into a baby, is known as the endometrium. This membrane is also responsible for a woman’s monthly menstrual cycle.
