About This Chapter
ILTS Biology: The Nervous, Immune and Endocrine Systems - Chapter Summary
The video and text lessons in this chapter can help you review information about the brain, immune system and nervous system as you prepare for the ILTS Biology test. Concepts examined include:
- How antibodies fight off infections
- Why we develop antibiotics and vaccines for pathogens
- How homeostasis is achieved in our bodies
- Human brain structure and function
- How the nervous system controls environmental awareness
- What happens when a neuron fires off its impulses
Our instructors will aid you in navigating each topic with fun video and text lessons you can enjoy on the go with your mobile device. Make sure you have a solid grasp of the main points by reviewing the text transcripts. There's even a printable worksheet that you can use for offline study.
ILTS Biology: The Nervous, Immune and Endocrine Systems - Chapter Objectives
In order to become a certified biology teacher in Illinois, you must pass the ILTS Biology exam. The exam's questions are divided into six subareas. The questions on material in this Nervous, Immune and Endocrine Systems chapter are incorporated into the Life Science subarea of the ILTS Biology test.
Both our lesson quizzes and the ILTS test are multiple-choice, so the quizzes offer solid practice in this format. The answer keys on the quizzes also link back to specific parts of the video lessons. If you answer a question incorrectly, it's easy to use those links to jump back to the lesson for review.
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.
2. 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.
3. Homeostasis in the Human Body
Homeostasis is the term we use to describe the reasonably stable internal environment of your body. Learn how parts of your body communicate with each other to maintain this state of homeostasis, and how negative feedback loops work.
4. The Human Brain: Structure & Functions
The human brain can be divided into three sections. In this lesson, we'll examine the hindbrain, midbrain, and forebrain, as well as the major structures in each. We'll also cover the functions of major brain structures.
5. The Human Immune System: Inflammation & Antibodies
A body as efficient as ours deserves an equally efficient immune system to protect it. Luckily for us, the efficiency of the immune system is its greatest strength, as this lesson demonstrates.
6. Pathogens, Viruses, Antibiotics & Vaccines
Pathogens, including viruses, are the cause of much of the sickness in the world today. Luckily, in the last few decades we have developed a range of tools to use against them, especially antibiotics and vaccines.
