amniochorionmembran
Amniochorionmembran, commonly referred to as the amniochorionic membrane, is the fetal membrane formed by the fusion of the amnion and chorion surrounding the developing embryo and fetus. The fusion creates a single, continuous membrane that encloses the amniotic cavity and contributes to the fetal membranes supporting pregnancy.
Formation and structure: The amnion arises from the inner cell mass (epiblast), while the chorion develops from
Function: The amniochorionmembran provides mechanical protection for the fetus and helps maintain the intrauterine environment by
Clinical significance: Disruption or premature rupture of the amniochorionmembran can lead to premature rupture of membranes
