Document Summary

Most babies are born healthy, but development can also go wrong. In this chapter, we will look at the stages of prenatal development, some of the factors that can adversely affect this development and promising advances in treatment and prevention of the causes of developmental damage. Learning objectives 4. 1 - trace the changes that occur in the three stages of prenatal development: name the three stages of prenatal development and provide 3 major developmental changes that occur during each stage. The extraordinary growth of the individual from ovum and sperm to a viable infant is a three- stage process (zygote, embryo, and fetus).
