Type of sensations carried by nociceptors are_________________?
Correct answer: D. Pain
- A. Touch.
- B. Temperature.
- C. Pressure.
- D. Pain
Explanation
Nociceptors are free nerve endings that respond to potentially damaging mechanical, thermal, or chemical stimuli and produce the sensation of pain. They are responsible for warning the body about tissue injury rather than detecting ordinary touch or pressure. The likely alternative is temperature, because extreme heat or cold can activate nociceptors, but their characteristic sensation is pain.

About Receptors
Receptors are specialized cells or proteins that detect stimuli such as light, sound, pressure, temperature and chemicals, then initiate responses through sensory or hormonal pathways. Questions distinguish sensory receptors from effectors, compare receptor types, and examine stimulus conversion into nerve impulses, including the roles of rods, cones, chemoreceptors and mechanoreceptors.
