Final answer:
Repeated arousal leads to increased production of catecholamines, as the adrenal glands release more of these hormones to prepare the body for fight or flight in response to stress or perceived threats.
Step-by-step explanation:
The question asks about the effect of repeated arousal on the production of catecholamines, specifically epinephrine and norepinephrine. These hormones are released by the adrenal medulla as a part of the fight-or-flight response, which is triggered by the sympathetic stimulation during stressful situations. Repeated arousal and the associated sympathetic stimulation can lead to increased secretion of these hormones. This is because the adrenal glands are activated to release catecholamines in response to stress, fear, emotions, exercise, and hypoglycemia, adapting the body to take direct action. Hence, the option C, Increased catecholamine production, is the correct answer since the body needs to prepare for the perceived threat or to flee from it, resulting in higher levels of catecholamines with repeated arousal.
