Learning the Nervous System

 Chapters 14 - 19

.  This tends to be a difficult unit of study, but you have many tools which will aide your successful learning. NOTE:  There are 6 chapters for this material on the skeletal system. REMEMBER!  When you come to the tools, you will only see the link to your online learning center.  Select each chapter individually and proceed to do the materials you have done in the past for each topic.  There is no substitute for learning by touching the structures and even coloring them in your Visual Analogy Guide and using the  Anatomy and Physiology revealed CD  You have approximately 1.5 weeks to complete this task.  Enjoy the stimulation this unit brings!

At the end of the study of this system, the successful student will be able to:

• The following sources of information will help you master the  the nervous system and the related structures for which you are responsible.

1. McGraw Hill website:  online Learning Center text material has great potential to help you learn the many components of anatomy and Physiology:

1. Body Smart which has animations to help you learn the basic components of the body's systems
2. Do the multiple choice, matching, and labeling for each chapters 14-19.
3. Use your Anatomy and Physiology revealed OFTEN, studying the interactive images, not just watching them.
4. Practice, practice, practice and then practice more.  There is a lot of material in these 6 chapters and you will have to spend at least twice as much time as you think you will need to to actually master all this critical material.

2. Textbook:  Read the objectives.  Use them as a guide when you 

   1. skim read the chapter to get a feel for the content and how the different topics are related

   2. reread the chapter look for the critical points and preparing for lecture

   3. study the chapter to learn the critical content

   4. review the chapter preparing for the quizzes and exams

3. Lecture:    Attend all lectures.  Use them to 

   1. identify important points

   2. ask questions of points not well understood in the text

   3. measure your learning comprehension

4. Lab:     Attend your scheduled lab and take advantage of open times to continue to study  
               Use your labs to correlate text structures to actual specimens in lab

5. You may find the glossary helpful for terminology understanding and to learn how to pronounce the words.  If you have forgotten how to call up the glossary, return to the introduction and reread the directions.  There are so many new terms that if you don't practice pronunciation at the same time you master the meaning, you will eventually find yourself very, very confused.  Adult learners remember via words stored in memory.  Without the sound that goes with the word, you will have difficulty retaining the work and its meaning.
