Question

Which of the following is least likely to result in the release of epinephrine (adrenaline) from the adrenal glands?

• A. Competing in an athletic event
• B. First day of college after X
• C. Falling asleep during a lecture
• D. Taking a test while unprepared

Answer 1

Answer: (C)

Falling asleep during a lecture

Epinephrine is normally produced by both the adrenal glands and certain neurons. It plays an important role in the fight-or-flight response by increasing blood flow to muscles, the output of the heart, pupil dilation, and blood sugar. Every emotional response has a behavioral component, an autonomic component and a hormonal component. The hormonal component includes the release of epinephrine, an adrenomedullary response that occurs in response to stress and that is controlled by the sympathetic nervous system. The major emotion studied in relation to epinephrine is fear.

Therefore, the correct answer is option C.
