Question 1

Correct Answer:

A good answer will include the following key points.
- The two divisions are the sympathetic and the parasympathetic divisions.
- The sympathetic division increases arousal and uses energy.
- The parasympathetic division slows the body and stores and conserves energy.
- Example: A stressful situation, such as giving a speech, causes increased sympathetic activity and arousal. When the speech is over, the parasympathetic division slows body functions to normal.
