Solution

The correct option is D

the adrenal medulla, leading to increased secretion of epinephrine and norepinephrine


The correct option is option D.

Explanation for correct option:

  1. The adrenal medulla secretes two emergency hormones: epinephrine and norepinephrine (adrenaline and noradrenaline).
  2. They're also known as "fight" or "flight" hormones. In an emergency or in response to stress, these are rapidly secreted.
  3. Sweating increased respiration rate and pulse, and enhanced alertness are some of the responses they cause.
  4. Glycogenolysis and lipolysis are also stimulated.

Final Answer: Fight­ or­ flight reactions cause the activation of the adrenal medulla, leading to increased secretion of epinephrine and norepinephrine.
