Humans have a homeostatic thermostat present in a specified portion of the brain that is:
Correct answer: D. Hypothalamus
- A. Lateral ventricle
- B. Thalamus
- C. Spinal cord
- D. Hypothalamus
Explanation
The hypothalamus is a section of the brain that controls thermoregulation. If hypothalamus senses internal temperature growing too hot or too cold, it will automatically send signals to the skin, glands,muscles,and organs, which will respond in various ways to return temperature to tropical range

About Thermoregulation
Thermoregulation maintains body temperature through negative feedback controlled mainly by the hypothalamus. It covers vasodilation and vasoconstriction, sweating, shivering, changes in metabolic heat production and behavioural responses, while distinguishing heat loss by radiation, conduction, convection and evaporation from temperature regulation itself.
