Meissner corpuscles are the receptors for

Correct answer: D. Touch

  • A. Temperature
  • B. Pain
  • C. Pressure
  • D. Touch

Explanation

Meissner corpuscles are integral to the human sensory system, specifically involved in detecting light touch. These mechanoreceptors are located just beneath the skin's surface, particularly in areas like fingertips and lips, where sensitivity is high. They enable the perception of fine details and textures, which is why the correct answer is D. The other options are incorrect because temperature is detected by thermoreceptors, pain by nociceptors, and pressure by other mechanoreceptors like Pacinian corpuscles.

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.
