Prenatal development refers to the process by which a human embryo or fetus develops during pregnancy, from conception to birth. This development occurs in a sequential and organized manner and is typically divided into three main periods: the germinal period, the embryonic period, and the fetal period. Each of these stages is characterized by distinct developmental milestones and is influenced by both genetic and environmental factors. Understanding the periods of prenatal development and the role of environmental influences is crucial in the study of life span psychology, as experiences in the womb can have lasting effects on physical, cognitive, and emotional development. Periods of Prenatal Development 1. Germinal Period (Conception to 2 Weeks) The germinal period begins at conception when the sperm fertilizes the egg to form a zygote. The zygote contains the complete set of genetic material (46 chromosomes) that determines the individual's traits. Over the next few days, the zygote undergoes rapid cell division, forming a blastocyst. This blastocyst travels down the fallopian tube and implants itself into the lining of the uterus by the end of the second week. During this stage, development is primarily biological and cellular. The key events include cell division, migration, and the beginning of cell differentiation, where ___ _____ _____ ______ ____.
