Which action of the adrenal medulla directly affects the sympathetic nervous system?
1. Arousal and wakefulness
2. Fight-or-flight response
3. Sensations of pain and touch
4. Ability to walk and speak
Correct Answer: 2
Rationale 1: Arousal and wakefulness are not related to catecholamine release from the adrenal medulla.
Rationale 2: The fight-or-flight response is directly related to the release of catecholamines—such as epinephrine and norepinephrine—from the adrenal medulla.
Rationale 3: Sensations of pain and touch are not related to catecholamine release from the adrenal medulla.
Rationale 4: Ability to walk and speak is not related to catecholamine release from the adrenal medulla.
Global Rationale: The fight-or-flight response is directly related to the release of catecholamines—such as epinephrine and norepinephrine—from the adrenal medulla. Arousal, wakefulness, sensations of pain and touch, and the ability to walk and speak are not related to catecholamine release from the adrenal medulla.
