The receptors for hearing and equilibrium are the example of:

Correct answer: A. Mechanoreceptors

  • A. Mechanoreceptors
  • B. Thermoreceptors
  • C. Nociceptors
  • D. Photoreceptors

Explanation

Both hearing and balance are detected by hair cells in the inner ear that respond to the mechanical bending of their stereocilia, so they are mechanoreceptors. Chemoreceptors respond to chemicals, thermoreceptors to temperature, nociceptors to damaging stimuli and photoreceptors to light, none of which drives the inner ear.

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.
