Question

The ossicles (the three tiny bones in the middle ear) are responsible for __________.
A.
converting sound vibrations into neural signals
B.
relaying sound vibrations to the eardrum
C.
vibrating in response to sound waves
D.
amplifying sound vibrations from the eardrum

Answer 1

D. The ossicles (malleus, incus, stapes) transmit and amplify vibrations from the tympanic membrane to the oval window of the inner ear — they do not convert vibrations into neural signals (hair cells do) nor relay vibrations to the eardrum.
