Which part of the brain regulates body temperature?

Correct Answer: HypothalamusYour Answer: C
✅ Correct Answer: C — Hypothalamus
The Hypothalamus is a small but vital region of the brain (part of the diencephalon) that acts as the body's 'thermostat'. It monitors blood temperature and regulates body temperature by: initiating sweating (for cooling), causing shivering (for warming), regulating blood vessel dilation/constriction, and controlling metabolic heat production. Normal body temperature is 37°C (98.6°F).
❌ Why other options are wrong:
• A. Cerebrum — Cerebrum is the largest part of the brain responsible for conscious thought, memory, language, and voluntary movement; not body temperature regulation.
• B. Cerebellum — Cerebellum controls balance, coordination, and fine motor movements; not temperature regulation.
• D. Medulla oblongata — Medulla oblongata controls involuntary functions like breathing, heart rate, and blood pressure; not body temperature.
📝 Important Note: Hypothalamus = thermostat of the body. Also controls hunger, thirst, sleep, emotions, and hormone secretion (via pituitary gland). Fever occurs when hypothalamus resets to a higher set point. Key brain function fact for SSC CGL.
