About This Chapter
Who's It For?
Anyone who needs help learning or mastering material on the sympathetic and parasympathetic nervous systems will benefit from the lessons in this chapter. There is no faster or easier way to learn about the sympathetic and parasympathetic nervous systems. Among those who would benefit are:
- Students who have fallen behind in understanding what the sympathetic and parasympathetic nervous systems are, their functions and their structures
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning about biology (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about the sympathetic and parasympathetic nervous systems
- Students who struggle to understand their teachers
- Students who attend schools without extra biology 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 Sympathetic & Parasympathetic Nervous 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 Sympathetic & Parasympathetic Nervous Systems chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any question about the sympathetic and parasympathetic nervous systems. 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 sympathetic and parasympathetic nervous systems unit of a standard human biology course. Topics covered include:
- Overview of and positive and negative feedback in the sympathetic and parasympathetic nervous systems
- Nervous systems function
- Interaction between the external environment and the nervous system
- Structures of the nervous system
- Function and types of neurons
- Myelin sheath and nodes of ranvier
- Function of meuroglia
- Physiology and anatomy of the brain
- Types and functions of sensors, receptors and sensory nerves
1. 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!
2. What is a Scotoma? - Definition, Types & Causes
A scotoma is an interruption or break in the visual field, surrounded by a remaining normal visual field. This lesson is about scotoma and the types and causes of this visual disorder.
3. 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!
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. Positive and Negative Feedback in the Sympathetic and Parasympathetic Nervous System
In this lesson, you'll study positive and negative feedback in the sympathetic and parasympathetic nervous systems. You'll also learn why we have a fight or flight instinct and how it works.
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. Types of Neurons: Sensory, Afferent, Motor, Efferent & More
There are many types of neurons in your body that help you see, smell, hear, and move. In this lesson, you'll learn more about afferent, efferent, sensory, and motor neurons.
8. The Myelin Sheath, Schwann Cells & Nodes of Ranvier
The myelin sheath is an essential part of our nervous system. Learn more about this neuron component, explore the nodes of Ranvier, and discover why Schwann cells are crucial for neuron survival.
9. Neuroglia: Function & Definition
In this lesson, you'll learn about the unsung heroes of your nervous system. These cells don't get a lot of attention, but without them, it would be difficult for your neurons to do their job and protect themselves against invaders.
10. Sensory Nerves: Types and Functions of Sensors and Receptors
In this lesson, we will explore what gives you the ability to sense temporary and sustained pressure, touch, and vibration. In addition, we'll touch base on certain nerves that allow you to sense the coolness of an ice cube in your mouth or the sensation of warmth on your skin.
11. Sensory Nerves and Receptors of Muscles and Tendons
Your body is able to sense its position in the environment. This is critical for movement, playing basketball, or even sitting still. Find out what this means as we explore proprioceptors, muscle spindles, and tendon organs.
12. The Brain Hemispheres: Left Brain/Right Brain Communication and Control
Ever heard of a split personality? How about a split brain? Well, we can't be sure about the personality one, but brains can be split in two! In this lesson, you'll learn that and much more on how the brain communicates within itself.
13. 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.
14. 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.
