In the autonomic nervous system, what distinguishes the sympathetic division from the parasympathetic division?
Understand the Problem
The question is asking for the distinction between the sympathetic and parasympathetic divisions of the autonomic nervous system. Specifically, it seeks to identify which of the provided options correctly describes one of the divisions in relation to the other.
Answer
Sympathetic is 'fight or flight'; Parasympathetic is 'rest and digest'.
The sympathetic division is responsible for the 'fight or flight' response, activating the body during perceived threats or danger. In contrast, the parasympathetic division restores the body to a calm, 'rest and digest' state after the threat has passed.

The sympathetic division is responsible for the 'fight or flight' response, activating the body during perceived threats or danger. In contrast, the parasympathetic division restores the body to a calm, 'rest and digest' state after the threat has passed.
More Information
The sympathetic division prepares the body for emergencies by increasing heart rate, dilating pupils, and redirecting blood flow to muscles. The parasympathetic division slows the heart rate, constricts pupils, and promotes digestion.
Tips
A common mistake is confusing the roles of the two divisions, often attributing calming functions to the sympathetic division or energizing functions to the parasympathetic division.
