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.
Fertilisation (also known as conception, fecundation and syngamy) is the fusion of gametes to initiate the development of a new individual organism. In animals, the process involves the fusion of an ovum with a sperm, which first creates a zygote and then leads to the development of an embryo.llogamy, which is also known as cross-fertilization, refers to the fertilization of an egg cell from one individual with the male gamete of another. Autogamy which is also known as self-fertilization, occurs in such hermaphroditic organisms as plants and flatworms; therein, two gametes from one individual fuse.
