A patient touches a rough surface and identifies its texture through the skin. Which receptor type is primarily involved in detecting this mechanical stimulus?
Correct answer: A. Mechanoreceptor
- A. Mechanoreceptor
- B. Thermoreceptor
- C. Photoreceptor
- D. Nociceptor
Explanation
Mechanoreceptors respond to physical distortion such as touch, pressure, vibration, and stretch. Thermoreceptors detect temperature, photoreceptors detect light, and nociceptors detect potentially damaging stimuli.

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.
