Compare with Definitions
Endometrium
The endometrium is the inner epithelial layer, along with its mucous membrane, of the mammalian uterus. It has a basal layer and a functional layer; the functional layer thickens and then is shed during menstruation in humans and some other mammals, including apes, Old World monkeys, some species of bat, the elephant shrew and the Cairo spiny mouse.
Decidua
The decidua is the modified mucosal lining of the uterus (that is, modified endometrium) that forms in preparation for pregnancy. It is formed in a process called decidualization under the influence of progesterone.
Endometrium
The glandular mucous membrane that lines the uterus.
Decidua
A mucous membrane lining the uterus, modified during pregnancy and shed at parturition or during menstruation.
