Transmission of sound through the middle ear would result in ______________________.
A)amplification of the pressure vibrations
B)stimulation of middle ear receptor cells
C) opening of the eustachian tube
D) increased firing rate in sensory axons associated with the tympanic membrane

Question

Quizplus · Accepted Answer

The middle ear contains three small bones (ossicles) that transmit vibrations from the eardrum to the inner ear. This transmission results in an amplification of the pressure vibrations, specifically, a multiplication by a factor of about 20. This amplification is necessary because the inner ear is filled with fluid, which offers more resistance to the pressure vibrations than air does.
