Which type of the receptors are present in the ear__________________?
Correct answer: B. Mechanoreceptors
- A. Chemoreceptors
- B. Mechanoreceptors
- C. Photoreceptors
- D. Thermoreceptors
Explanation
Hearing and balance depend on hair cells that respond to mechanical displacement caused by sound waves or movement of fluid in the inner ear. Therefore, the receptors of the ear are mechanoreceptors. The likely alternative is photoreceptors, but photoreceptors detect light in the retina, not mechanical vibrations in the 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.
