The Chorion
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.
The protective sac surrounding the embryo is formed by the amniotic membrane and the amniotic fluid which together create the amniotic sac. This sac serves to cushion and protect the developing embryo during pregnancy.
The extraembryonic membrane that forms a fluid-filled sac is the amnion. It helps protect and cushion the developing embryo by surrounding it with amniotic fluid.

The chorionic membrane is a thin, outermost membrane that surrounds the fetus in the womb. It is composed of layers of cells derived from both the embryo and the mother and plays a role in the exchange of nutrients and waste between the fetus and the mother. The chorionic membrane eventually fuses with the amniotic membrane to form the amniotic sac.

The chorion is the outermost fetal membrane. It is formed by the fusion of the extraembryonic mesoderm with the inner surface of the trophoblasts. Its function is to aide in the production of the placenta.
The allantois membrane and the chorion form the placenta in mammals. The chorion is the outermost fetal membrane that encases the embryo and later fuses with the maternal tissue to form the placenta.
The structure that surrounds the yolk and transports nutrients to the embryo is called the vitelline membrane. This membrane is responsible for facilitating the exchange of nutrients and waste products between the yolk and the developing embryo during embryonic development.
The fluid-filled sac surrounding the developing embryo or fetus is called the amniotic sac. It is filled with amniotic fluid that protects and cushions the fetus, helping to regulate its temperature and provide room for movement.
The chorion is a membrane that surrounds the embryo and provides a protective barrier. It helps regulate gas exchange between the developing embryo and the surrounding environment, allowing for the exchange of oxygen and carbon dioxide. It also plays a role in facilitating nutrient transfer during embryonic development.
The chorion is the outer membrane surrounding the embryo that is continuous with the placenta, the highly vascular structure that acts as a physical communication between the mother and the embryo.
