Biological Development - Chapter Summary and Learning Objectives

The stages of biological development start when a baby is still in the womb. In fact, quite a bit of growth and development occurs within the prenatal period. As you will learn in these lessons, there are different prenatal stages at which the baby's body is forming. Each stage is quite important. The infant stage is also a time of critical growth and development, and important milestones continue as a person grows, even into adulthood. This chapter will cover different aspects of biological development, starting in the prenatal stages going through adulthood. Some of the things you'll learn include:

  • The prenatal stages of development
  • Brain development before birth
  • Important growth and development stages in infants
  • Maturation of adolescents
  • Physical, psychological and emotional changes in adults
  • Potential problems during the birthing process
