, pl.en·do·me·tri·a
(en'dō-mē'trē-ŭm, -trē-ă), [TA]The mucous membrane comprising the inner layer of the uterine wall; it consists of a simple columnar epithelium and a lamina propria that contains simple tubular uterine glands. The structure, thickness, and state of the endometrium undergo marked change with the menstrual cycle. The blastocyst implants into the endometrium making the uterus gravid. If implantation does not occur, the superficial part of the endometrium is shed during the (hemorrhagic) menstrual phase of the uterine cycle.

Etymology: Gk, endon + metra, womb
the mucous membrane lining of the uterus, consisting of the stratum compactum, the stratum spongiosum, and the stratum basale. The endometrium changes in thickness and structure with the menstrual cycle. The stratum compactum and the stratum spongiosum constitute the pars functionalis and are shed with each menstrual flow. The pars functionalis is known as the decidua during pregnancy, when it underlies the placenta. Compare myometrium, parametrium.

endometrium
The inner mucous membrane lining of the womb (uterus) that undergoes changes in structure and thickness at different stages of the menstrual cycle, and much of which is shed at menstruation.endometrium
the lining of the uterus in female mammals, being a glandular MUCUS membrane that undergoes changes during the OESTRUS CYCLE during which it builds up under the influence of OESTROGEN in preparation for receiving the fertilized egg. Where fertilization does not occur, it regresses, or in the case of humans, anthropoid apes and Old-World monkeys, it breaks down over a few days, producing bleeding. See MENSTRUAL CYCLE.Endometrium
The mucosal layer lining the inner cavity of the uterus. The endometrium's structure changes with age and with the menstrual cycle.
