The inner of the membranes composing the sac, bag of waters, which envelops the fetus in the uterus. It consists of two layers, an inner or epiblastic, the true amnion, and an outer or mesoblastic, the false amnion. The latter, which is in contact with the chorion, either unites with that or disappears. The sac lined by the amnion contains the liquor amnii in which the fetus floats.

The innermost of the enveloping membranes of the foetus :-so called because first observed in the sheep (?), It is thin, transparent, perspirable, and possesses many delicate colourless vessels, which have not been injected. It is generally considered to be produced by a fold of the external layer of the germinal membrane, rising up, and gradually enveloping the embryo. Its external surface is feebly united to the chorion by areolar and vascular filaments. Its inner surface is polished, and is in contact with the body of the foetus and the liquor amnii.
