About This Chapter

The Nervous Systems chapter of this Campbell Biology Companion Course helps students learn the essential lessons associated with nervous systems. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Nervous Systems textbook chapter.

How It Works:

  • Identify the lessons in the Campbell Biology Nervous Systems chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the nervous systems topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • The major nervous system functions
  • The makeup of the central and peripheral nervous systems
  • Effects of the sympathetic and parasympathetic nervous systems
  • Major structures of the brain and their functions
  • Cognitive changes that occur in middle adulthood
  • Types of psychotic disorders

Nervous System Overview: Central & Peripheral

1. Nervous System Overview: Central & Peripheral

What happens in your nervous system when you react to stimuli? Did you know that the brain is sometimes uninvolved with reflexes? Find out the answer to these questions, and more, in this lesson on the human nervous system.

Functions of the Nervous System

2. 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!

The Central and Peripheral Nervous Systems

3. 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.

The Sympathetic and Parasympathetic Nervous Systems

4. 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!

Early Brain Development: Major Parts & Functions

5. Early Brain Development: Major Parts & Functions

In this lesson, we take a look at your brain when you were the size of a peanut and your brain the size of a pea. What major structures did your brain have back then? What were they called? And most interestingly, how do these structures affect your life today?

Brain Structures and Functions Part I

6. Brain Structures and Functions Part I

The brain's complexity can often be difficult to understand because it serves so many important functions. In this lesson, you'll get a little help from Nrr, the alien biologist, who will guide you through understanding the structure and functions of the human brain.

The Cerebral Cortex: Brain Structures and Functions Part II

7. The Cerebral Cortex: Brain Structures and Functions Part II

Check out this video lesson to learn about the four lobes of the human brain - the frontal, parietal, occipital and temporal. You'll learn about the functions and processes of each region.

Memory and Information Processing in Adults

8. Memory and Information Processing in Adults

During middle age, many people notice that they aren't as mentally sharp as they once were. During this lesson, we'll look at cognitive abilities that decline in middle adulthood, including information processing and working memory.

Psychotic Disorders of the Nervous System

9. Psychotic Disorders of the Nervous System

This lesson will discuss some psychotic disorders and their general causes. We will go over schizophrenia, delusional disorders, and mood disorders, such as depression and bipolar disorder.

Non-Psychotic Disorders of the Nervous System

10. Non-Psychotic Disorders of the Nervous System

In this lesson, we'll go over three main classes of non-psychotic disorders that affect the mind. We'll cover mood, anxiety, and personality disorders such as OCD, depression, SAD, and more.

Alzheimer's: History, Causes, and Treatments

11. Alzheimer's: History, Causes, and Treatments

We will learn about Alzheimer's in this lesson, which is a devastating disease of the brain. We'll discuss whom it affects most, why it occurs, what can be done about it, and much more.

Parkinson's Disease: Causes, Progression, and Treatments

12. Parkinson's Disease: Causes, Progression, and Treatments

This lesson will cover Parkinson's disease. It will inform you of what it is, what symptoms it causes, whom it affects most, why it occurs, and what treatment options exist. We'll explore everything from Lewy bodies to the substantia nigra.
