Final answer:
Nociceptors are specialized receptor cells that respond to potentially damaging stimuli and are responsible for transducing pain sensations.
Step-by-step explanation:
Nociceptors are a type of nociceptor, not a chemoreceptor. Nociceptors are specialized receptor cells that respond to potentially damaging stimuli and are responsible for transducing pain sensations. They are activated by mechanical, chemical, or thermal stimuli beyond a certain threshold, and play a crucial role in our ability to perceive pain.
