Question

From the list of structures that you ordered for hearing, which structure is the receptor that changes sound energy to action potential?

Answer 1

Inner ear contain receptors for sound,that changes sound energy into action potential

Organ of corti is the structure which converts sound energy into action potential,hair cells present in organ of corti converts sound energy into actionpotential.

Process:

Bones in the middle ear transmit vibrations to cochlea->pressure waves in cochlea->causes another membrane to vibrate binding its hair cells->bending depolarizes the membrane of special receptor and send action potential to brain via cranial nerve 8.
