the thin innermost layer of the extraembryonic membranes that contains the amniotic fluid; the membrane forms a closed sac in which the embryo and later, the fetus, is suspended and protected
A thin but tough extraembryonic membrane of reptiles, birds and mammals that lines the chorion and contains the fEtus and the amniotic fluid around it. [Biology_Online][VHOG]
Structures homologous to the four extraembryonic membranes of reptiles and birds appear in mammals: amnion, chorion, yolk sac, and allantois.[well established][VHOG]
