About This Chapter
How it works:
- Identify the lessons in Glencoe Biology's Nervous System chapter with which you need help.
- Find the corresponding video lessons within this companion course chapter.
- Watch fun videos that cover the nervous system topics you need to learn or review.
- Complete the quizzes to test your understanding.
- If you need additional help, re-watch the videos until you've mastered the material or submit a question for one of our instructors.
Students will learn about:
- Neuron structure and function
- Sensory, afferent, efferent and motor neurons
- Schwann cells and nodes of Ranvier
- Central and peripheral nervous systems
- Sympathetic and parasympathetic nervous systems
- The olfactory bulb and nose
- Large structures of the eye

1. The Structure and Function of Neurons
In this video lesson, you'll learn about neurons, which are specialized cells in the nervous system. Check out how far neurons can send signals throughout the body and how depolarization is much like 'the wave' at a football game.
2. Types of Neurons: Sensory, Afferent, Motor, Efferent & More
There are many types of neurons in your body that help you see, smell, hear, and move. In this lesson, you'll learn more about afferent, efferent, sensory, and motor neurons.
3. The Myelin Sheath, Schwann Cells & Nodes of Ranvier
The myelin sheath is an essential part of our nervous system. Learn more about this neuron component, explore the nodes of Ranvier, and discover why Schwann cells are crucial for neuron survival.
4. Functions of the Nervous System
In this lesson, we'll watch Timmy as he plays in his backyard. Watch what happens when he tries to catch a butterfly, hears a mean dog bark, and scrapes his knee. All of Timmy's reactions are tied to his nervous system. For a full explanation of what goes on in the human nervous system, check out the video!
5. The Central and Peripheral Nervous Systems
Did you know that hammerhead sharks and platypuses share a special type of sensory neuron that humans and most other animals don't have? In this lesson, you'll find out what that sensory neuron and a whole lot of others can do. You'll also learn how the nervous system is organized and the differences between the central and peripheral nervous systems.
6. The Sympathetic and Parasympathetic Nervous Systems
In this lesson, you'll learn about two subdivisions of the autonomic nervous system - the sympathetic and parasympathetic nervous systems. Watch as a hiker, Phil, runs away from a terrifying bear and see how these systems react to the impending danger!
7. Taste, Touch & Smell: Proprioception & the Somatosensory System
How do taste, touch and smell work? Also, what is proprioception? Throughout this lesson, you'll get a detailed description on each of these remarkable senses.
8. The Sense of Smell: Olfactory Bulb and the Nose
How does the sense of smell relate to your eyes? Why can we smell something in the first place? These questions and many more will be answered as we look into the olfactory bulb, chemoreceptors, cranial nerve I, and the olfactory nerve.
9. The Eye and Eyesight: Large Structures
Would you be able to see anything without a lens in your eye? Does the lens change shape? Does the iris? What structure gives you your eye color? Find out all of this and about things like the ciliary muscles and the cornea as we delve into this lesson.
10. Receptors of the Back of the Eye: Retina, Rods, Cones & Fovea
Find out how we see the world in color, what rods and cones are, and how camera film fits into all of this. In addition, you'll find out what the retina is and what gives you the ability to see at night.
11. The Ear: Middle Structures and Hearing Functions
Find out about the malleus, incus, and stapes. You'll learn about the smallest bones in your body and find out what the ossicles are for. Finally, you'll find out how the oval window plays an important role in the transmission of sound.
12. From Misuse to Abuse: Distinction & Effects
This lesson will differentiate drug misuse and abuse. You will also learn how the central nervous system is affected by drugs and what other effects drugs have upon the body.
