Amnion: the inner of the two membranes enveloping the embryo.
The embryo when about to hatch throws off the egg-shell and amnion in a few seconds.
Only in the chancel were they protected by sheep's amnion stretched on frames.
The amnion contains a fluid known by the name of liquor amnii.
Both it and the stalk of the yolk-sack are enveloped by the amnion (am).
It adheres to the amnion and supplies it with blood-vessels (Bischoff).
Superficial to it is the amnion, and below it is the yolk sac.
This second fold gives rise to the amnion, and is limited entirely to the somatopleure.
The amnion in fact begins to pulsate slowly and rhythmically, and by its pulsation the embryo is rocked to and fro in the egg.
During the eighth, ninth, and tenth days, the amnion does not undergo any very important changes.
