About This Chapter
Who's It For?
Anyone who needs help learning or mastering nervous, endocrine, and immune systems material will benefit from the lessons in this chapter. There is no faster or easier way to learn about the nervous, endocrine, and immune systems. Among those who would benefit are:
- Students who have fallen behind in understanding the function of the nervous, endocrine, and immune systems
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning human physiology (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about the nervous, endocrine, and immune systems
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources
How It Works:
- Find videos in our course that cover what you need to learn or review.
- Press play and watch the video lesson.
- Refer to the video transcripts to reinforce your learning.
- Test your understanding of each lesson with short quizzes.
- Verify you're ready by completing The Nervous, Endocrine, and Immune Systems chapter exam.
Why It Works:
- Study Efficiently: Skip what you know, review what you don't.
- Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
- Be Ready on Test Day: Use The Nervous, Endocrine, and Immune Systems chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any nervous, endocrine, and immune systems question. They're here to help!
- Study With Flexibility: Watch videos on any web-ready device.
Students Will Review
This chapter helps students review the concepts in a nervous, endocrine, and immune systems unit of a standard science course. Topics covered include:
- What the nervous system does
- How the body regulates temperature
- Glucose regulation and diabetes
- The purpose of hormones and how they are produced
- How the immune system operates
1. 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!
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.
3. 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!
4. Homeostasis and Temperature Regulation in Humans
Do you wonder how your body is able to maintain a consistent temperature? Have you ever questioned why you get goosebumps when you're cold? This lesson will introduce you to homeostasis and answer your questions about body temperature regulation and reactions, like goosebumps.
5. Homeostasis of Glucose Levels: Hormonal Control and Diabetes
In this lesson, we'll look at how the body uses hormones to maintain homeostasis of blood glucose levels, what happens in people who have diabetes, and how diabetics can manage their disease.
6. 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.
7. Hormones: Definition, Function & Intro to the Endocrine System
This lesson introduces the endocrine system and provides a brief overview of each endocrine gland. It also provides the definition of hormones and describes their general function inside the body.
8. What Is the Pituitary Gland? - Functions, Hormones & Hypothalamus
In this lesson, we'll discuss the functions of the anterior and posterior portions of the pituitary gland, the hormones they release and the relationship with the hypothalamus.
9. The Thyroid Gland: Functions, Calcitonin & TSH
Your thyroid gland produces the hormones T3 and thyroxine (T4), which play a role in metabolism. Your thyroid also produces calcitonin, which helps regulate blood calcium levels. In this lesson, you will learn about the thyroid gland and its hormones, including how they are regulated by TSH.
10. What Is the Immune System? - Our Body's Defense Against Pathogens
In this lesson, you will be introduced to the immune system. You'll learn about the innate and adaptive immune system, Edward Jenner, haptens and immune tolerance.
11. The Anatomical Barriers of the Immune System
This lesson will cover the major anatomical barriers to infection of the innate immune system. We'll explore skin flora, gut flora, gastric acid, lysozymes, and the mucociliary apparatus.
12. What is Allostasis? - Definition, Allostatic Load & Example
In this lesson, you're going to learn about more than one possible definition of allostasis. Then, you'll learn about the definition of allostatic load. Both concepts will be explained with examples in mind.
13. Allostasis vs. Homeostasis: Differences & Relationship
This lesson will clearly define homeostasis and allostasis and then distinguish exactly how they are truly different concepts or if they're actually exactly the same ones.
