The sympathetic nervous system is responsible for the fight or flight response, which is activated in times of stress or danger. The sound of a fire alarm triggering an evacuation would qualify as a stressful situation, meaning the sympathetic nervous system is dominant. It prepares the body to respond to this stress by increasing heart rate, dilating pupils, and releasing adrenaline.
