The term 'Embryonic Membrane' refers to two membranes that form around the developing embryo in the uterus. The first membrane is the Caul, which is a thin, transparent membrane that covers the head and face of the fetus. The second membrane is the AMNION, which is a thin, transparent sac that encloses the fetus and contains the amniotic fluid. Together, these two membranes protect the developing embryo from infection and provide a supportive environment for growth and development.
