The Central Nervous System in the Human Body - Chapter Summary and Learning Objectives

The brain is the control center of the body. It is what tells our lungs to take air in and push it out, our heart to beat to keep blood moving and our fingers to move when we need them to. It helps keep our body temperature even and remind our eyes to blink so they don't dry out. Every movement and function of our bodies starts in the brain. Due to the many responsibilities of the brain, it is quite complex. Even the best scientists and doctors don't fully understand every detail about it. However, there have been many scientific discoveries about the brain and the general structure and function of the parts of the brain is rather well-known. In fact, that is what you'll be learning about in this chapter. Some of the things you can expect to learn include:

  • The development of the brain
  • The function of the brain stem
  • The major anatomical structures of the brain
  • The hemispheres of the brain
  • Blood supply in the brain
  • The role of cerebrospinal fluid

VideoObjective

Central Nervous System: Definition, Function & Parts

1. Central Nervous System: Definition, Function & Parts

The body is divided into many systems. In this lesson, you will learn about the parts that make up the nervous system and their functions to gain a better understanding of this critical system.

The Layers of the Meninges: Medical Vocabulary

2. The Layers of the Meninges: Medical Vocabulary

This lesson will cover the three layers of the meninges and important (potential) spaces between them. You'll learn about dura mater, arachnoid mater, pia mater, arachnoid granulations and other vocabulary related to the meninges.

The Brain: Structure and Function

3. The Brain: Structure and Function

Your brain is in charge of telling the rest of your body what to do. Learn about the parts of your brain including the cerebrum, the cerebellum, the brain stem and the pituitary gland and how they help you live, play and grow.

Parts of the Brain Stem: The Medulla Oblongata and Pons

4. 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.

Cerebellum: Definition & Function

5. 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.

Midbrain: Definition, Function & Structures

6. Midbrain: Definition, Function & Structures

In this lesson, we'll explore the midbrain, including where it's located, what structures compose it, and what its role is in the functions of your brain.

Diencephalon: Definition, Location & Function

7. Diencephalon: Definition, Location & Function

The diencephalon is a part of the brain that is responsible for many functions in the human body. In this lesson, you will learn about the diencephalon, including its location, parts, and functions.

What is the Limbic System in the Brain? - Definition, Functions & Parts

8. What is the Limbic System in the Brain? - Definition, Functions & Parts

The limbic system is composed of structures in the brain that deal with emotions (such as anger, happiness and fear) as well as memories. This article will address the limbic system, its parts and their functions in the human body.

What is the Cerebrum? - Definition, Functions & Location

9. 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.

Anatomy of the Spinal Cord: Function & Explanation

10. 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

11. 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.
