WebThe process in which the germ layers are formed during embryonic development is called gastrulation.

These three germ layers are ectoderm, endoderm and mesoderm which further undergo the process of organogenesis giving rise to ... WebDuring gastrulation the cells of the inner cell mass of blastocyst or blastula move in small mass to their new final location. Such movement of cells is called morphogenetic movements Gastrulation results in the formation of three germ layers: ectoderm, mesoderm and endoderm. Each germ layer gives rise to specific tissues, organs and organ-systems.
WebNeurulation is the formation of the neural tube from the ectoderm of the embryo. It follows gastrulation in all vertebrates. During gastrulation cells migrate to the interior of the embryo, forming the three germ layers: the endoderm (the deepest layer), the mesoderm (the middle layer), and the ectoderm (the surface layer) from which all tissues and organs will arise.
