    In this chapter, we will consider what happens during prenatal development, including the impact of teratogens. We will also discuss the impact that both the mother and father have on the developing fetus. 


    Learning Objectives: Prenatal Development

    • Describe the changes that occur in the three periods of prenatal development
    • Describe what occurs during prenatal brain development
    • Define teratogens and describe the factors that influence their effects
    • List and describe the effects of several common teratogens
    • Explain maternal and paternal factors that affect the developing fetus
    • Explain the types of prenatal assessment
    • Describe both the minor and major complications of pregnancy


    Now we turn our attention to prenatal development which is divided into three periods: The germinal period, the embryonic period, and the fetal period. The following is an overview of some of the changes that take place during each period.
