Ch 3: Function & Parts of the Nervous System

About This Chapter

Elevate your understanding of the function and different parts of the nervous system, including the peripheral nervous system, gray matter, and the spinal cord. If you are preparing for an exam or class discussion, these lessons and quizzes will help boost your confidence by testing your knowledge of the topics in advance.

Function & Parts of the Nervous System - Chapter Summary

In these lessons on the function and parts of the nervous system, you will learn about how the cerebellum and cerebrum work and also gain a clearer understanding of the brain stem. By the end of the chapter, you should be positioned to:

  • Discuss the parts and functions of the human nervous system
  • Distinguish the difference between the central and peripheral nervous systems
  • Recall where white matter and gray matter are found in the brain
  • Explain how the somatic and autonomic nervous systems help you with a range of activities
  • Describe how the sympathetic and parasympathetic nervous systems react to danger
  • Discuss the medulla oblongata and pons
  • Explain how the spinal cord works with the brain
  • List components and functions of a reflex arc

The easy to comprehend teaching style used by our expert educators will help you quickly get up to speed on the nervous system. A brief quiz is available for each lesson to test your knowledge of topics covered. Additionally, full transcripts of the video are available for each lesson.

The Human Nervous System: Parts & Functions

1. The Human Nervous System: Parts & Functions

Your nervous system allows you to experience the world around you and react to it. It's a complex system that's split into two main parts, the central nervous system and the peripheral nervous system. Read on to learn the parts and functions of the system.

The Central and Peripheral Nervous Systems

2. 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.

White Matter vs. Gray Matter: Difference & Medical Terms

3. White Matter vs. Gray Matter: Difference & Medical Terms

This lesson will define white matter vs. gray matter, explain why a color difference exists, and go over where each is found in the brain and spinal cord as well as their functions.

Functions of The Somatic & Autonomic Nervous Systems

4. Functions of The Somatic & Autonomic Nervous Systems

Learn how your peripheral nervous systems keeps the rest of the body in communication with the brain. Consider how two major subsystems help you out with a range of activities, from getting up in the morning to fighting off an attack.

The Sympathetic and Parasympathetic Nervous Systems

5. 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!

What is the Cerebrum? - Definition, Functions & Location

6. What is the Cerebrum? - Definition, Functions & Location

The cerebrum is a structure found in the brain. In this lesson, we will identify where the cerebrum is located in the brain and why it is vital to your everyday life.

Cerebellum: Definition & Function

7. Cerebellum: Definition & Function

The brain is one of the most complex organs in the body, and each part is responsible for a different set of functions. This lesson discusses the cerebellum and its function in the human body.

Parts of the Brain Stem: The Medulla Oblongata and Pons

8. Parts of the Brain Stem: The Medulla Oblongata and Pons

In this lesson, we'll learn how you are able to breathe without even thinking about it. You'll also find out why you breathe faster when you run. Finally, we'll learn where things as diverse as sneezing and blood pressure are controlled.

Anatomy of the Spinal Cord: Function & Explanation

9. Anatomy of the Spinal Cord: Function & Explanation

The spinal cord partners up with the brain to send information around the body as electrical signals. It tells the body what the brain wants and the brain what the body is feeling. This lesson explains how its structure helps accomplish this.

Reflex Arc: Definition, Components & Functions

10. Reflex Arc: Definition, Components & Functions

Sometimes our body can react in a split second, faster than it could take to send the information to the brain for processing. These reflexes are the subject of this lesson. We'll cover what a reflex arc is, as well as the cells involved and why they are needed.
