1.	The amnion of mammalian embryo is derived from(1) ectoderm and mesoderm(2) endoderm and mesoderm(3) mesoderm and trophoblast(4) ectoderm and endoderm
Answer» The correct option is(1) ectoderm and mesoderm Explanation: Amnion of mammalian embryo is derived from ectoderm and mesoderm. It is one of the extraembryonic membranes which is formed by the amniogenic cells of ectodermal origin on the inner side and somatopleuric extraembryonic mesoderm on outer side. This membrane acts as a shock absorber for the foetus, regulates foetal body temperature and prevents desiccation. The origin of other extraembryonic membranes is as follows Chorion Trophoectoderm and mesoderm. Allantois and Yolk sac Outer mesoderm and inner endoderm.
