Embryology is a branch of science that is related to the formation, growth, and development of embryo. It deals with the prenatal stage of development beginning from formation of gametes, fertilization, formation of zygote, development of embryo and fetus to the birth of a new individual. Two basic processes involved are growth and differentiation. These lead to formation of various tissues and organs in body specialized to perform specific functions. Neuroembryology is related to the development of central nervous system (brain and spinal cord) and peripheral nervous system (spinal, cranial, and autonomic nerves) in the body. These tissues develop from neural tube and neural crest cells. In this chapter we have described the origin and various stages of development of a multicellular, highly complex, and specialized nervous system from a single-celled zygote.
