The fetal membranes are the membrane that surrounds the fetus during pregnancy. The amnion and the chorion make up the fetus’s amniotic sac.
If you’re pregnant, you’ve probably heard the term “fetal membranes.” But what are they, exactly? And what do they do? In this blog post, we will discuss the fetal membranes and their role in pregnancy. We will also talk about the different types of fetal membranes and what happens when they rupture. Stay tuned for more information on this important topic!
What are fetal membranes?
The fetal membranes are the membrane that surrounds the fetus during pregnancy. The amnion and the chorion make up the fetus’s amniotic sac. The allantois and secondary umbilical vesicle are the other fetal membranes.
Development of the fetal membranes
The chorion is separated from the amnion by a chorionic fluid at first. The fusion of the amnion and chorion is completed at the end of the 12th week in development.
Types of fetal membranes
There are two types of fetal membranes: the amnion and the chorion.
The amnion is the inner layer of the fetal membranes. It is a thin, transparent membrane that covers the fetus and contains fluid. The chorion is a thicker, opaque membrane that covers the amniotic sac.
What is the role of fetal membranes?
The primary role of the fetal membranes is to protect the fetus from infection. It contributes to the formation of amniotic fluid. The amniotic fluid also cushions the fetus and prevents it from being compressed during pregnancy. In addition, the chorion helps to regulate the temperature of the fetus.
Intact membranes protect against ascending uterine infection and aid in the dilation of the cervix during delivery.
What happens when fetal membranes rupture?
Rupture of the fetal membranes is known as “the water breaks.” The membranes are ruptured, or the “water breaks” when a woman goes into labor. When the membranes rupture, amniotic fluid flows from the vagina. The flow varies from a trickle to a gush. A woman should contact her doctor or midwife as soon as the membranes have broken.
