Question

Which of the following function is not associated with middle ear?
(1) Amplification of sound wave
(2) Equilibrium of air pressure
(3) Transmission of sound wave from external ear to internal air
(4) Maintaining Static equilibrium
​

Answer 1

(4) Maintaining Static equilibrium is not associated with middle ear.

• Option (1) is a function of the middle ear because the three bones on the middle ear malleus, incus and stapes transfer sound waves.
• When sound waves transfers through these bones, it is also amplified.
• Option (2) is a function of the middle ear as middle ear has the structure referred as Eustachian tube for maintaining the equilibrium of air pressure.
• Option (3) is a function of the middle ear as the middle ear lies between the external ear and internal ear and is a passage in between for the transmission of sound waves.
• Option (4) is not a function of the middle ear as maintaining static equilibrium is a function of the inner ear. Hence, option (4) is the correct option.
