Receptors for hearing come under heading of___________?
Correct answer: B. Mechanical
- A. Chemical
- B. Mechanical
- C. Photo
- D. Nociceptors
Explanation
Hearing receptors respond to mechanical vibrations produced by sound waves, so they are mechanoreceptors. Students may choose chemical receptors because the receptor cells use chemical synapses, but the stimulus detected is mechanical movement, not a chemical substance.

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.
