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 an amniochorion?
An amniochorion is a collective term for the amnion and chorion together - a part of the reproductive system.
Membranes forms a protective sac that surrounds the embryo?
Amnion chorion yolksac allantois
What are the fetal membrane layers?
The fetal membrane layers are the Chorion, Amnion, Yolk sac, and Mesenchymal layer.
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 term for living substance that has pores that allows water to pass through?
Biological membrane, cell membrane, fetal membranes: amnion, chorion,
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 . . .
What is the membrane that forms a sac around an animal embryo?
The inner most membrane is the fluid filled amniotic sac, next is the yolk sac, where the first blood cell originates. The allantois forms near the yolk sac, while the chorion surrounds all the other ones.
Where is the chorion membrane located?
The Chorion is one of the membranes that exists during pregnancy between the developing fetus and it's mother. It allows the transfer of nutrients from the maternal blood to the fetal blood.
What is the population of Chorion company?
Chorion - company -'s population is 150.
