MEMBRANA SEROTINA Meaning and
Definition
-
Membrana serotina, also known as the decidua serotina or simply the serotina, is a biological term referring to a specialized layer of the endometrium in the uterus during pregnancy. It is a temporary structure that forms during the early stages of pregnancy, specifically in the third and final trimester.
This membrane serves a crucial role in the attachment and development of the placenta, which is vital for the exchange of nutrients and waste between the mother and the fetus. The membrana serotina, in combination with the chorionic villi of the fetus, forms the placental interface where these exchanges occur.
The membrana serotina develops from the decidua basalis, which is the deep layer of the endometrium that remains after implantation of the blastocyst. As pregnancy progresses, the decidua basalis undergoes changes and differentiation to form the membrana serotina.
The structure of the membrana serotina consists of maternal tissues, including endometrial glands and blood vessels, as well as fetal tissues, such as the villous trees of the chorion. These tissues fuse and intertwine, creating a unique interface that supports the growth and nourishment of the developing fetus.
Overall, the membrana serotina plays a crucial role in facilitating the exchange of nutrients and waste between the mother and the fetus, thereby supporting the growth and development of the fetus during pregnancy.
