Verified
When the warmth-sensitive receptors of the hypothalamus are stimulated,what physiological processes would be initiated?
A) Shivering and vasoconstriction
B) Peripheral vasodilation and shivering
C) Sweating and peripheral vasodilation
D) Sweating and vasoconstriction
Warmth-Sensitive Receptors
Sensory receptors in the skin and other organs that detect changes in temperature, particularly increases in warmth.
Hypothalamus
A region of the brain that plays a crucial role in hormone production, regulating bodily functions such as temperature, hunger, and sleep cycles.
Peripheral Vasodilation
The widening of blood vessels away from the heart, typically in the limbs, reducing blood pressure and increasing blood flow.

Final Answer :
C
Explanation :
When the warmth-sensitive receptors of the hypothalamus are stimulated, sweating and peripheral vasodilation are initiated. This allows the body to release heat and cool down. Shivering and vasoconstriction are initiated when the cold-sensitive receptors are stimulated, which helps to conserve heat and warm up the body.
