How does the hypothalamus mediate temperature regulation? A) Through the parasympathetic nervous system B) By release of triiodothyronine (T₃) C) Through the stimulation of epinephrine D) By stimulation of the renin-angiotensin-aldosterone system

Question

Quizplus · Accepted Answer

The hypothalamus mediates temperature regulation through the release of triiodothyronine (T₃), which acts on the thyroid gland to increase metabolic rate and generate heat. This helps to regulate body temperature when it is too low. When body temperature is too high, the hypothalamus triggers sweating and vasodilation to dissipate heat and cool the body down. The other options (A, C, and D) are not involved in temperature regulation by the hypothalamus.
