Quizplus · Accepted Answer

The loud bang in the kitchen is an external stressor that triggers the body's alarm reaction, which activates the sympathetic nervous system, resulting in an increase in heart rate, respiration, and blood pressure. This response is a typical first stage of the general adaptation syndrome (GAS), as described by Hans Selye. Choice A is incorrect because the parasympathetic nervous system is responsible for reducing arousal levels and promoting relaxation, which is not the case here. Choice C is incorrect because the amygdala is responsible for processing emotional stimuli and triggering fear response, so it is not shut down but rather activated in this situation. Choice D is incorrect because the resistance phase occurs after prolonged exposure to stress, and it involves adapting to the stressor and returning to baseline levels of physiological function. The occurrence of a single stressful event, like a loud bang, does not constitute the resistance phase.
