Which brain region regulates body temperature?

Which brain region regulates body temperature?

• A. Hypothalamus
• B. Cerebrum
• C. Cerebellum
• D. Brainstem

Answer: (A)

The brain region that acts as the body's thermostat is the hypothalamus. It receives input from thermoreceptors in the skin and inside the body, compares this information to a set point, and then triggers the right responses to keep temperature steady. If the body is too hot, the hypothalamus promotes cooling responses like sweating and vasodilation. If it’s too cold, it triggers warming measures such as shivering and vasoconstriction. The cerebrum handles higher thinking, the cerebellum coordinates movement, and the brainstem governs basic autonomic functions, but they don’t establish and regulate the body’s temperature set point the way the hypothalamus does.
