Document Summary
Chapter #11 human development across the life span. There are two themes that permeate the study of human development: transition, continuity. Development is the sequence of age-related changes that occur as a person progresses from conception to death. We will divide the life span into four periods: the prenatal period (between conception and birth, childhood, adolescence, adulthood. The prenatal period extends from conception to birth, usually encompassing nine months of pregnancy: development during the period is remarkably rapid. The course of prenatal development: germinal stage. The germinal stage is the first phase of prenatal development, encompassing the first two weeks after conception. A zygote is created and within 36 hours, rapid cell division begins the mass of cells slowly migrates along the mother"s fallopian tube to the uterine cavity. On the 7th day, the cell mass begins to implant itself in the uterine wall, which takes about a week (many zygotes are rejected at this point)
