- Amnion, in reptiles, birds and mammals is a membrane forming a fluid-filled cavity (the amniotic sac) that encloses the embryo.
- During development the amnion arises by a folding of a mass of extra- embryonic tissue called the somatopleure.
- Lined with ectoderm and covered with mesoderm, the amnion contains a thin transparent fluid in which the embryo is suspended, thus providing a cushion against mechanical injury.

The amnion is a membrane that surrounds the developing embryo of mammals. It is filled with amniotic fluid and provides a protective environment for the developing fetus.
Explanation:
The amnion is derived from both the ectoderm and mesoderm layers of the developing embryo. During the process of gastrulation, the ectoderm and mesoderm layers form the embryonic disc. The amnion develops from the ectoderm layer on the dorsal surface of the embryonic disc, which folds over and encloses the embryo, forming a fluid-filled sac. The mesoderm layer then surrounds the amnion, forming the chorion.
In summary, the amnion of the mammalian embryo is derived from both the ectoderm and mesoderm layers of the developing embryo.
