Which two hormones are released by the adrenal medulla during a fight or flight response?
Insulin and glucagon
Dehydroepiandrosterone and estradiol
Ghrelin and kisspeptin
Epinephrine and norepinephrine
The Correct Answer is D
a. Insulin and glucagon: These hormones are produced by the pancreas and regulate blood glucose levels, not involved in the fight or flight response.
b. Dehydroepiandrosterone and estradiol: These are adrenal and gonadal hormones involved in sexual function and other roles, but not in the immediate stress response.
c. Ghrelin and kisspeptin: Ghrelin is involved in hunger signaling, and kisspeptin in reproductive hormone signaling, neither are involved in the stress response.
d. Epinephrine and norepinephrine: These are the primary hormones released by the adrenal medulla in response to stress, preparing the body for a fight or flight response by increasing heart rate, blood pressure, and blood glucose levels.
