Which type of receptor detects changes in tissue damage and contributes to the sensation of pain?
Correct answer: C. Nociceptor
- A. Photoreceptor
- B. Mechanoreceptor
- C. Nociceptor
- D. Chemoreceptor
Explanation
Nociceptors detect potentially damaging mechanical, thermal, or chemical stimuli and initiate pain signals. Photoreceptors detect light, mechanoreceptors detect forces such as pressure, and chemoreceptors detect chemicals.

About Nervous System and Special Senses
The nervous system covers neurons, neuroglia, nerve impulses, synapses, reflex arcs, and the organization of the central and peripheral nervous systems. It also explains the autonomic divisions and the receptors and pathways for vision, hearing, balance, taste and smell, distinguishing sensory reception from conscious perception.
