Correct answer: C. Neurulation
- A. Gastrulation
- B. Neurogenesis
- C. Neurulation
- D. Both A and B
- E. None of these
Explanation
The process of formation of neural tube is known as neurulation. Neurulation is a critical early stage in the embryonic development of vertebrates, including humans, where the neural tube is formed. The neural tube is the precursor to the central nervous system, which includes the brain and spinal cord. Neurulation is a complex and highly coordinated process that occurs during the early stages of embryonic development.Neurulation begins after the process of gastrulation, where the three primary germ layers (ectoderm, mesoderm, and endoderm) are formed. In neurulation, the ectoderm gives rise to the neural plate, a flat sheet of cells.Neurulation is a pivotal event in embryonic development because it sets the stage for the formation of the entire central nervous system. Any defects or abnormalities in the process can lead to serious congenital disorders, including neural tube defects (NTDs) such as spina bifida and anencephaly.

About Growth and Development
Embryonic development covers fertilization, cleavage, formation of the blastula and gastrula, germ layers, organ formation and differentiation. Regeneration describes the replacement of lost tissues or body parts, whereas ageing involves gradual cellular and physiological changes linked to reduced repair, altered metabolism and declining organ function.
