Question

multiple choice question
what is the part of the brain that regulates and maintains body temperature?

pituitary gland
pineal gland
thalamus
hypothalamus

Explanation:

To solve this, we analyze each option:

• Pituitary gland: Mainly involved in hormone secretion, not primary temperature regulation.
• Pineal gland: Regulates sleep - wake cycles via melatonin, not temperature.
• Thalamus: Acts as a sensory relay station, not for temperature maintenance.
• Hypothalamus: A key brain region that regulates body temperature (along with other homeostatic functions like hunger, thirst).

Answer:

D. Hypothalamus
