Ch 2: Neurons Study Guide

About This Chapter

The Neurons chapter of this Nervous System Study Guide course is the simplest way to master neurons. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure you learn the essentials of neurons.

Who's It For?

Anyone who needs help learning or mastering neuron structure and function will benefit from the lessons in this chapter. There is no faster or easier way to learn about neurons. Among those who would benefit are:

  • Students who have fallen behind in understanding how sensory and motor neurons send and receive signals
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about neurons
  • 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 Neurons 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 Neurons chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any neurons 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 neurons concepts covered in a standard science course. Topics covered include:

  • Neuron structure
  • Functions of neurotransmitters
  • Sensory, motor, afferent and efferent neurons
  • The myelin sheath and Schwann cells
  • Nodes of Ranvier and action potential
  • Synaptic transmission and the neuromuscular junction
  • Astrocytes, oligodendrocytes, ependymal cells and radial glia
  • Effects of aging on neurons
  • Neuroplasticity

What is a Neuron? - Definition, Parts & Function

1. What is a Neuron? - Definition, Parts & Function

What are the parts of a neuron? You'll watch Neuron Garciaparra work up a sweat as he throws baseballs to demonstrate the structures and functions of the billions of neurons that reside in your body.

The Structure and Function of Neurons

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.

The Function of Neurotransmitters

3. The Function of Neurotransmitters

Like people, neurons need to communicate with each other in order to work together to function. In this lesson, we'll examine neurotransmitters, including what they do, how they do it, and what happens after they've done their job.

Types of Neurotransmitters

4. Types of Neurotransmitters

What do neurotransmitters have to do with choosing a hiking trail up a mountain? In this lesson, we'll look at the two main types of neurotransmitters, inhibitory and excitatory, including the functions and examples of each.

Types of Neurons: Sensory, Afferent, Motor, Efferent & More

5. 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.

The Myelin Sheath, Schwann Cells & Nodes of Ranvier

6. 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.

The Neuromuscular Junction: Function, Structure & Physiology

7. The Neuromuscular Junction: Function, Structure & Physiology

A neuromuscular junction is a synapse between a motor neuron and skeletal muscle. This lesson describes the events of synaptic transmission leading to contraction of skeletal muscle. Myasthenia gravis is described as a neuromuscular disease.

Neuroglia: Function & Definition

8. 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.

How Age Affects Our Neurons: Major Changes & Their Effects

9. How Age Affects Our Neurons: Major Changes & Their Effects

This lesson briefly explores the process of aging at a cellular level. The neuron is the most vital component of the brain and follows a particular path when aging.

What is Neuroplasticity? - Definition & Examples

10. What is Neuroplasticity? - Definition & Examples

Is your brain preprogrammed and unchangeable or adaptive and malleable? As you watch this video, you'll explore how the brain, a more resilient and resourceful machine than any computer, responds to damage and new experiences.

Interneurons: Definition & Function

11. Interneurons: Definition & Function

The central nervous system is designed to connect sensory and motor pathways for reflexes. Interneurons are the cells that serve as that connection. This article addresses interneurons and their function in the nervous system.
