Question
The hormones response are responsible for the 'fight-or-flight'
Correct Answer
Option D is the correct answer.
Detailed Explanation
The 'fight-or-flight' response is primarily mediated by the catecholamines adrenaline (epinephrine) and noradrenaline (norepinephrine), which are released from the adrenal medulla and sympathetic nerve endings. These hormones increase heart rate, blood pressure, blood glucose, and redirect blood flow to muscles. Cortisol and aldosterone are involved in stress response (cortisol) and electrolyte balance (aldosterone) but are not the primary mediators of the immediate fight-or-flight response.
Hint
Which hormones are released from the adrenal medulla and directly prepare the body for rapid action?
