The Brain

In this lesson you will learn about how your body communicates with itself through the use of the nervous system. Your body uses nerve cells called neurons and communicates with them using a series of electrical impulses called action potentials. Use the menu above to learn more about how your body communicates with itself and what factors may affect this communication. It is recommended that you move from left to right using the menu as you move through the lesson to better understand neural communication. After you have completed the lesson go to the practice area where you can put your knowledge to the test by trying to solve a few case studies. Good luck!


Lesson Objectives

After completing the lesson you will be able to:

  1. List the structural components of neuron.
  2. Describe the sequence of events involved in a nerve impulse.
  3. Describe the function of neurotransmitters.
  4. Describe the affects of increased or decreased levels of neurotransmitters.
  5. List different psychoactive drugs.
  6. Describe the affects of psychoactive drugs on neural communication.
