Amnion is the membrane that covers the embryo. Chorion is the membrane that covers the amnion, the yolk sac, and the allantois. The space delimited by the chorion and the amnion is called amniotic cavity and it is filled with aminiotic fluid. The amniotic cavity has the functions of preventing desiccation of the embryo and of protecting it against mechanical shocks.

What are twins that come from the same fertilized egg?
Unlike the single baby, this fertilized egg cell will split into two separate embryos, and grow into identical twins. This remarkable event takes place during the first week after fertilization, and can happen at several different times:At the two cell stage on days 1 to 3At the early blastocyst stage on days 4 to 6Or in the late blastocyst stage on days 7 to 9The stage at which the egg cell splits determines how the twins will implant in the uterine lining, and whether or not they share an amnion, chorion, and placenta. Basically, the earlier the splitting occurs, the more independently the twins will develop in the uterus. So, a pair of identical twins that split during the two-cell stage will each develop its own amnion, chorion, and placenta.Twins that split during the late blastocyst stage will share an amnion, chorion, and placenta.

What is the difference between chorion and trophoblast?
The chorion is the outermost membrane surrounding the embryo, while the trophoblast is the outer layer of cells of the blastocyst responsible for implantation and placenta formation in early pregnancy. Specifically, the trophoblast gives rise to the chorion during embryonic development.
What are the fetal membrane layers?
The fetal membrane layers are the amnion and chorion. The amnion is the innermost layer that surrounds the fetus and is filled with amniotic fluid, providing protection and cushioning. The chorion is the outermost layer that helps form the placenta and plays a role in nutrient and waste exchange between the mother and the fetus.
What are the three layer of membrane that make up the placenta?
Allantois, amnion, and chorion
What is an amniochorion?
An amniochorion is a collective term for the amnion and chorion together - a part of the reproductive system.
What is the membrane that forms the embryonic side of the placenta?
The placenta is completely formed by 10 weeks, by the joining of the decidua basalis (maternal side) and chorionic villi (fetal side). The chorion and amnion are the placental membranes. The Chorion is the membrane furthest from the embryo, and the amnion in the inner layer that is closest to the embryo.
What is the outermost layer of two membranes surrounding the embryo?
The outermost layer of two membranes surrounding the embryo is the amnion. The two membranes are the amnion and the chorion, which together form the amniotic sac that surrounds and protects the developing embryo.
What is the term for living substance that has pores that allows water to pass through?
Biological membrane, cell membrane, fetal membranes: amnion, chorion,
Membranes forms a protective sac that surrounds the embryo?
The embryonic sac, or amniotic sac, is composed of a membrane called the amnion. The amnion serves to protect the embryo by providing a physical barrier against external threats and a cushioned environment for development. Additionally, the amnion secretes amniotic fluid which helps to regulate temperature, provide buoyancy, and prevent desiccation of the embryo.
What is the medical term meaning two sacs that enclose the embryo and what are their combining forms?
The chorion and the amnion form the amniotic sac. Their respective combining forms are chorio- and amnio-.
Willl a females water break twice if she is having twins?
I'm not entirely sure . . . but I'm learning about animal development now. Embryos are surrounded by a few extraembryonic membranes: the chorion (outermost), the amnion (holds the "water"), the allantois (part of umbilical cord) and the yolk sac (contains no yolk, but where blood cells form). Twins most commonly separate either before the chorion develops or after the chorion develops and before the amnion does (so the embryos each have their own amnion and "water"). If the latter is the case, it seems like it would be reasonable to assume that two amnions and thus two "waters" would have to break. But, again, I'm not 100 percent sure . . .
Compare the functions of a human embryonic membranes with those inside a bird's egg?
The human embryonic membranes, including the amnion, chorion, yolk sac, and allantois, support and protect the developing embryo in the womb by providing nourishment, gas exchange, and waste elimination. In birds, the amnion, chorion, yolk sac, and allantois inside the egg serve a similar function by enclosing the developing embryo and providing necessary nutrients, oxygen, and waste removal for growth and development. Both systems play a vital role in sustaining the developing organism until it is ready to survive independently.
What is the population of Chorion company?
Chorion - company -'s population is 150.
