The sympathetic division in the autonomic nervous system gives us the fight or flight response.

Question

BlackTom AI · Accepted Answer

This true/false item asks about the role of the sympathetic division of the autonomic nervous system (ANS).
Option 1: True. The sympathetic branch is classically associated with the fight-or-flight response. Activation prepares the body for rapid action by increasing heart rate, dilating bronchioles, redirecting blood flow to muscles, dilating pupils, and releasing stress hormones. These changes collectively support quick physical and metabolic responses to perceived threats or demanding situations.
Option 2: False. Saying the sympathetic division does not participate in fight-or-flight would be inaccurate because this response is a hallmark of sympathetic activity. The parasympathetic division, by contrast, generally promotes rest-and-digest functions, not the rapid mobilization characteristic of fight or flight. Therefore attributing fight-or-flight to the sympathetic system is incorrect if one confuses its role with the parasympathetic system or understates its involvement.
Additional nuance: While the sympathetic system contributes through neural pathways and adrenal release of catecholamines to produce systemic changes, the parasympathetic system provides opposing actions that promote conservation of energy and maintenance activities. Recognizing this balance helps avoid oversimplifying the ANS divisions.
