Welcome to the Nervous System

This unit is all about the nervous system. You'll learn about the different branches of the nervous system and each of their functions. You'll learn about how nerve transmissions take place, how reflexes happen, and about the senses of sight and hearing.

Follow the directions in each of the lessons in the table of contents. Do everything listed on each page as doing it all will help you learn the information well. If you do the minimum through these lessons you'll find much difficulty through this course.

Each lesson may have a video, a practice worksheet, a quiz, activity etc. and they are all there to help you understand the information better. If you see something highlighted in blue, it is a hyperlink for you to click. If you see something highlighted in green, it is also a link to click and it is an assignment/quiz which will be for marks.

Module 1 Review and Quiz

Before doing the final module 1 quiz, make sure to go through these resources to make sure that you know what you know, and that you know what you don't know.

The first step is to go through the detailed nervous system notes to make sure you're familiar with all the points learned throughout the unit.

The next unit system notes are less detailed so that you should be able to fill in extra info based on what you know.

Finally, go through the concept guide. The concept guide has just a few things listed on it, and you will want to be able to read the the words and be able to explain the processes/ define the words. you want to be able to explain and define everything on the concept guide without looking at the PowerPoint/textbook readings.

1. Here are detailed nervous system notes

2. Nervous system review notes

3. Here is the concept guide. You will want to be able to verbalize and explain everything from this document.

You are now through the nervous system unit, and can begin on module 2, in which you will learn about hormones and the endocrine system.
