Question

what type of receptor cell is responsible for transducing pain stimuli?

○ chemoreceptor

○ mechanoreceptor

○ photoreceptor

○ nociceptor

○ osmoreceptor

Explanation:

• Chemoreceptors detect chemical stimuli (e.g., in taste, smell).
• Mechanoreceptors respond to mechanical forces (e.g., touch, pressure).
• Photoreceptors detect light (in vision).
• Nociceptors are specialized to detect potentially damaging stimuli (pain).
• Osmoreceptors sense osmotic pressure (related to fluid balance).

Answer:

Nociceptor
