Ch 48: Campbell Biology Chapter 48: Neurons, Synapses, and Signaling

About This Chapter

The Neurons, Synapses, and Signaling chapter of this Campbell Biology Companion Course helps students learn the essential lessons associated with neurons, synapses, and signaling. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Neurons, Synapses, and Signaling textbook chapter.

How It Works:

  • Identify the lessons in the Campbell Biology Neurons, Synapses, and Signaling chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the neurons, synapses, and signaling topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • The makeup and roles of neurons
  • Steps involved in information processing
  • Resting potential formation
  • Action potential steps
  • The structure and function of the neuromuscular junction
  • The function of neurotransmitters in the body

The Structure and Function of Neurons

1. 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.

Information Processing: Encoding, Storage & Retrieval

2. Information Processing: Encoding, Storage & Retrieval

How does your brain remember information and recall it later? In this lesson, you'll look at the steps your brain takes as it processes data from short-term memory and stores it as long-term memory.

Establishing Resting Potential of a Neuron

3. Establishing Resting Potential of a Neuron

What happens to a neuron when it's not firing? In this lesson, we'll examine the resting potential of a neuron, including what it is, how it works, and how channels, gates, and pumps help establish the resting potential after a neuron fires.

Action Potential: Definition & Steps

4. Action Potential: Definition & Steps

How do brain cells communicate with each other? View this lesson to find out about action potentials of neurons, how that helps them to communicate with each other, and what happens when neurons become more or less polarized.

The Neuromuscular Junction: Function, Structure & Physiology

5. 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.

What is a Neurotransmitter? - Definition, Types, Function & Examples

6. What is a Neurotransmitter? - Definition, Types, Function & Examples

How do our bodies communicate with our brains and vice versa? In this video, you'll see how neurons and neurotransmitters can be likened to billions of tiny baseball players engaged in a non-stop game of catch.
