DECIDUA MENSTRUALIS Meaning and
Definition
-
Decidua menstrualis, also known as menstrual decidua, is a specialized tissue that forms within the uterus during the menstrual cycle. It is composed of endometrial tissue, which lines the inner cavity of the uterus, and undergoes cyclical changes in response to hormonal fluctuations.
During the proliferative phase of the menstrual cycle, under the influence of estrogen, the endometrium thickens and becomes rich in blood vessels in preparation for potential pregnancy. If fertilization and implantation of an embryo do not occur, the endometrial tissue enters the secretory phase.
During the secretory phase, progesterone is released, causing the endometrium to become even thicker and more specialized. This phase ensures a conducive environment for embryo implantation and early development. However, if fertilization does not occur, hormone levels drop, leading to the shedding of the endometrial lining as menstrual blood.
Decidua menstrualis is the term used to describe the specific condition of the endometrial lining during menstruation. The tissue undergoes significant structural changes, including breakdown and shedding of the functional layer that had thickened during the secretory phase. This shedding is accompanied by bleeding from blood vessels within the endometrium.
Decidua menstrualis is an essential part of the menstrual cycle, as it allows the uterus to renew its inner lining every month. This process is crucial for the reproductive health of women, preparing the uterus for potential pregnancy while also ensuring the elimination of the lining in the absence of fertilization.

Etymology of DECIDUA MENSTRUALIS
The word "decidua" comes from Latin, derived from "deciduus" meaning "falling off" or "shedding". In the context of anatomy, decidua refers to the lining of the uterus that is shed during menstruation or after pregnancy.
The term "menstrualis" is also derived from Latin, specifically from "mensis" meaning "month" or "menstrual cycle". Therefore, "decidua menstrualis" refers to the shedding of the uterine lining during the menstrual cycle.
