Nervous System Lessons

Lesson 4 - Saltatory Conduction

In this lesson you will learn about

1. Watch this video to learn about a little bit more about the action potential and to learn about saltatory conduction, which is how nerve impulses can go really fast. 

2. Once you've watched the video answer the questions from this document. These questions will help make sure that you correctly understand the information from the lesson.

3. Read Chapter 11 pages 377-378 from the textbook for a deeper understanding of this material.

i) I can explain how saltatory conduction increases nerve impulse speed.

ii) I can explain how nerve impulses are all or none.
