Question

The following structures of the mammalian auditory system is involves in transduction of pressure changes in receptor potential ?

• A. The Tympanic membrane
• B. The ear ossicles
• C. The oval window
• D. Organ of Corti

Answer 1

Answer: (A)

The Tympanic membrane

The tympanic membrane also called are drum is a thin membrane that receives sound vibrations or pressure and then change it into receptor potentials from the outer ear and transmits it to auditory or ear ossicles (tiny bone in tympanic ). The oval window is a membrane-covered opening that leads from middle to inner ear and Organ of Corti is the sensory organ for hearing and located in the cochlea.

So the correct option is "The Tympanic membrane'.
