About This Chapter
The Brain - 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
|Early Brain Development: Major Parts & Functions||Discover how the brain develops, including the development of the major parts.|
|Brain Structures and Functions Part I||Explore the brain stem, hippocampus, hypothalamus, thalamus, olfactory bulb and cerebellum.|
|The Cerebral Cortex: Brain Structure and Functions Part II||Examine the cerebral cortex and how it functions.|
|Gross Anatomy of the Human Brain: Major Anatomical Structures and Terminology||Study the major structures of the brain and medical terminology for parts of the brain.|
|The Brain Hemispheres: Left Brain/Right Brain Communication and Control||Analyze how the two hemispheres of the brain communicate with each other and why that is important.|
|Parts of the Brain Stem: The Medulla Oblongata and Pons||Find out why the brain stem is so important to the functioning of the brain.|
|Brain Blood Supply: Anatomy & Diagrams||See how the arrangement of blood vessels and the flow of blood in the brain are essential to preventing death.|
|Cerebrospinal Fluid in the Brain: Functions & Production||Learn how the cerebrospinal fluid protects the brain.|
1. Gross Anatomy of the Human Brain: Major Anatomical Structures and Terminology
In this video, you'll find out how and why we divide our brain into major sections. It's not just random names and games. You'll learn about where these divisions occur, what we call them, and what they separate.
2. 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.
3. 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.
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.
5. Brain Blood Supply: Anatomy & Diagrams
You'll never look at a shopping mall the same way again once you learn in this lesson how similar it is to your brain. We'll also find out why connections between blood vessels are important and how your brain protects itself against toxic substances in your blood.
6. Cerebrospinal Fluid in the Brain: Functions & Production
In this lesson, you'll learn that you have holes in your brain and that it's actually a good thing! You'll also find out how your brain uses a water cushion for protection and where this water cushion is made.
