How embryo turn from gastrula to neurula
Explain how does the embryo turn from gastrula into neurula? Also how is the neural tube formed? Mention the embryonic origin of nervous system in vertebrates?
Expert
The neurula phase is characterized by the look of the neural tube beside the dorsal area of the embryo. The progress of mesoderm in that area induces the separation of ectodermal cells just above. These cells then differentiate creating the neural tube. So the source of the nervous system is ectoderm (the similar germ layer which gives birth to the skin).
