Question

Amplification and transmission of the vibrations received by tympanum into the inner ear are done by:

• A. Eustachian tube
• B. Ear ossicles
• C. Perilymph
• D. Cochlea

Answer 1

The correct option is B

Ear ossicles

Ear ossicles amplify and transmit the vibrations of tympanum to the internal ear. The three tiniest bones in the body form the coupling between the vibration of the eardrum and the forces exerted on the oval window of the inner ear. Resting against the oval window of the inner ear is the stapes (stirrup), which articulates with the middle ossicle called the incus (anvil). The incus articulates with the malleus (hammer), whose "handle" is attached to the internal surface of the tympanic membrane (eardrum).
