Question

Quizplus · Accepted Answer

The malleus, incus, and stapes, collectively known as the ossicles, function to amplify the vibrations of sound waves as they are transmitted from the eardrum to the oval window of the cochlea. This amplification is crucial for the efficient transfer of sound energy into the fluid-filled inner ear, where it can be converted into neural signals.
