Which statement best describes how temperature sensitivity varies across the skin?

• A. Regions tend to be more sensitive to either heat or cold, but not both
• B. Regions can be sensitive to both heat and cold
• C. Some regions only detect warmth
• D. No region detects temperature

Answer: (C)

Temperature detection in the skin comes from two types of receptors: warm and cold. These receptors aren’t spread evenly, so different skin areas vary in how strongly they respond to warm versus cold stimuli. Because some regions have a higher sensitivity to warmth and a relatively smaller or less noticeable response to cold, it’s reasonable to say that some areas mainly detect warmth. That’s why this statement best captures the pattern: regional differences in temperature sensitivity aren’t all-or-nothing, and some areas are biased toward warmth detection more than cold. The other options are too absolute or inaccurate because temperature sensing isn’t completely exclusive to one modality in any region, and temperature is detected by receptors across the skin.
