Ch 5: Prenatal Development Concepts

About This Chapter

Watch online prenatal development video lessons and learn the prenatal stages of life, the layers of the embryo, things that can effect the prenatal environment, and more.

Prenatal Development Concepts - Chapter Summary and Learning Objectives

Investigate the earliest stages in the human life cycle - those that take place before birth. In this chapter, instructors will explain the prenatal stages and how the brain develops through them. You will be introduced to the theories of growth and development that inform our current understanding of prenatal development and the relevant vocabulary associated with this topic. At the end of this chapter, you should be able to:

  • Describe the prenatal life support systems
  • Differentiate among the three principles of growth
  • Explain the stages of brain development
  • Understand the effects of drug use, smoking, alcohol use, eating a high fat diet, and other common prenatal health hazards
  • Understand what happens just before and just after fertilization

Ovulation to Implantation: Oocyte's Path through Uterine Tubes

1. Ovulation to Implantation: Oocyte's Path through Uterine Tubes

Follow the female's egg as it leaves the ovary and travels down the uterine tube on its way to the uterus - all with hopes of meeting up with a male's sperm along the way.

Prenatal Stages and Development: Germinal, Embryonic & Fetal Period

2. Prenatal Stages and Development: Germinal, Embryonic & Fetal Period

In the 9 months before a baby is born, there is an enormous amount of prenatal development. In this lesson, you will explore the following stages of prenatal development: the germinal period, the embryonic period, and the fetal period.

Principles of Growth and Development

3. Principles of Growth and Development

Is there a pattern to how human growth and development takes place? This lesson will examine some universal principles of growth and development in order to help you find the answer to this question.

The Placenta and the Fetus: Structure and Function

4. The Placenta and the Fetus: Structure and Function

Have you ever wondered how a baby eats before it's born or if babies go to the bathroom while still inside their mother? In this lesson, you will learn about the placenta and how it works to ensure a fetus stays well-nourished and healthy before birth.

The Amnion and the Umbilical Cord: Structure and Function

5. The Amnion and the Umbilical Cord: Structure and Function

The prenatal environment is an important part of an embryo's development. Watch this lesson to find out more about the prenatal environment, including the importance of the amnion and umbilical cord and what they do.

Gastrulation and the 3 Germ Layers (Ectoderm, Endoderm & Mesoderm)

6. Gastrulation and the 3 Germ Layers (Ectoderm, Endoderm & Mesoderm)

Gastrulation is a key process in embryonic development - it's how a simple ball of cells begins to grow into a fully functioning being! Watch this lesson to learn about a key process in the development of almost all multicellular organisms.

Prenatal Stages of Brain Development

7. Prenatal Stages of Brain Development

The prenatal brain develops at an amazing speed. This lesson provides an overview of this brain development throughout the three trimesters of pregnancy and highlights key stages.

The Prenatal Environment and Hazards to Healthy Prenatal Development

8. The Prenatal Environment and Hazards to Healthy Prenatal Development

In this lesson, learn about the prenatal environment and what can be harmful to prenatal development. Learn about the hazards of drugs, alcohol, tobacco, disease and environmental pollutants during pregnancy.

The Impact of Mother's Emotional and Physical State on the Prenatal Environment

9. The Impact of Mother's Emotional and Physical State on the Prenatal Environment

An unborn child and its mother are connected both physically and emotionally. Learn how prenatal development is affected by both the emotional and physical state of the mother in this lesson.

Prenatal Genetic Counseling and Assessment
