QUESTION
Cold stress increases the hormonal output of?
OPTIONS
(A) Adrenal medulla
(B) Adrenal cortex
(C) Thyroid
(D) All of the above
ANSWER
(D) All of the above
EXPLANATION
All of the above is the correct option because cold stress activates coordinated endocrine responses involving the adrenal medulla, adrenal cortex and thyroid axis to increase metabolic activity and support thermogenesis. Adrenal medullary catecholamines provide rapid responses, adrenal cortical hormones support longer-term adaptation, and thyroid hormones increase basal metabolic activity, so all listed glands contribute.
