Quizplus · Accepted Answer

The adrenal medulla secretes epinephrine and norepinephrine, which are known as stress hormones. These hormones act to supplement the effects of sympathetic stimulation, which is the division of the autonomic nervous system responsible for the fight or flight response. They increase heart rate, blood pressure, and respiratory rate, among other physiological responses.
