The amnion is a membranous sac which surrounds and protects the embryo. It is the first of the three cavities (amnion, chorion and yolk sac) in the embryo and is formed on 8 dpc.hen first formed, the amnion is in direct contact with the body of the embryo, but about the fourth or fifth week, amnionic (amniotic) fluid (liquor amnii) begins to accumulate within it. As the volume of the fluid increases, the amnion expands and ultimately adheres to the inner surface of the chorion.
