Question

question 5 of 10
if you can feel hot and cold in your hand but you cannot tell if anyone is touching your hand, there may a problem with the _____ in your hand.

a. mechanoreceptors
b. proprioceptors
c. chemoreceptors
d. infrareceptors

Explanation:

To solve this, we analyze each option:

• Mechanoreceptors detect mechanical stimuli like touch, pressure, etc. If one can't tell if someone is touching the hand (a mechanical stimulus) but can feel hot/cold (temperature, detected by thermoreceptors), a problem with mechanoreceptors fits.
• Proprioceptors sense body position/movement, not touch.
• Chemoreceptors detect chemicals (e.g., in taste/smell), not touch.
• Infrareceptors aren't a standard type for touch; they might relate to infrared (heat) but the issue here is touch detection, not heat sensing (since hot/cold is felt, so thermoreceptors work). So the problem is with mechanoreceptors.

Answer:

A. mechanoreceptors
