Explanation:
Detailed explanation-1: -The region of the embryo containing the neural progenitor cells is referred to as the neural plate. The first sign of neural tube development is the appearance of two ridges that form along the two sides of the neural plate on approximately E21 (Fig.
Detailed explanation-2: -The neural tube formation during gestational development is a complicated morphogenic process that requires various cell signaling and regulation by a variety of genes. It starts during the 3rd and 4th week of gestation.
Detailed explanation-3: -Early development In a process called neurulation, the neural folds curve upward and fuse to form the neural tube, which will eventually become the CNS.
