Sympathetic nervous system mediates:

Sympathetic nervous system mediates:

• A. Rest and digest
• B. Fight or flight
• C. Fine motor control
• D. Slow metabolic rate

Answer: (B)

The sympathetic nervous system activates the body’s rapid response to stress, preparing for action with the fight-or-flight response. This includes speeding up the heart, widening airways, dilating pupils, and mobilizing glucose for quick energy. The option rest-and-digest belongs to the parasympathetic system, which calms the body and promotes digestion and energy conservation. Fine motor control involves somatic (voluntary) motor pathways, not the autonomic system. A slower metabolic rate would not fit with sympathetic activation, which actually increases metabolic readiness. Therefore, the sympathetic nervous system mediates the fight-or-flight response.
