Neurulation refers to the folding process in vertebrate embryos, which includes the transformation of the neural plate into the neural tube. The embryo at this stage is termed the neurula.rior to neurulation, during the migration of epiblastic endoderm cells towards the hypoblastic endoderm, the notochordal process opens into an arch termed the notochordal plate and attaches overlying neuroepithelium of the neural plate.
Origin of the epidermis. Following neurulation, the precursor of the epidermis is formed from the cells covering the embryo-the ectoderm. This then becomes 2 layers, the outer forming the periderm and the inner forming the basal layer or stratum basale.A further layer is formed from the basal layer called the spinous layer or stratum spinosum.The basal and spinous layers are termed the Malphigian layer, the cells of which then divide to produce the granular layer or stratum granulosum.his then becomes 2 layers, the outer forming the periderm and the inner forming the basal layer or stratum basale. A further layer is formed from the basal layer called the spinous layer or stratum spinosum.
