Life span is divided into 4: the prenatal period, between conception and birth, childhood, adolescence, adulthood. Conception occurs when fertilization creates a zygote- a one-celled organism formed by the union of a sperm and an egg. A great deal of important development occurs before birth during prenatal period. The prenatal period is divided into three phases: (1) the germinal stage (the first two weeks) (2) the embryonic stage (two weeks to two months), and (3) the fetal stage (two months to birth) Begins when zygote is created through fertilization zygto becomes a microscopic mass off multiplying cell 7th day the mass implants itself on the uterine wall.
