When a person is exposed to temperature extremes, why is it difficult to distinguish hot from cold objects?
A) Temperature perception requires more than one type of receptor.
B) Temperatures above 37 degrees centigrade actually stimulate the cold receptors.
C) At extremes, pain receptors are stimulated by both very hot and very cold objects.
D) Most temperature receptors cannot differentiate hot from cold.
E) Pain receptors are inhibited by both very hot and very cold objects.
Temperature Perception
The sensory detection and interpretation of changes in external and internal temperature by the body.
Cold Receptors
Specialized nerve receptors in the skin that detect cold temperatures and signal this information to the brain.
Pain Receptors
Sensory nerve cells that respond to damaging or potentially damaging stimuli by sending nerve signals to the spinal cord and brain, triggering the sensation of pain.

Final Answer :
C
Explanation :
At extreme temperatures, both very hot and very cold objects stimulate pain receptors, making it difficult to distinguish between the two based on temperature alone. This is because the sensation of pain takes precedence over the specific sensation of hot or cold.
