Question

which represents the correct order in which vibrations pass from the outer to inner ear?
auditory canal; ear drum; ossicles; cochlea
cochlea; ear drum; auditory canal; ossicles
ear drum; auditory canal; cochlea; ossicles
ossicles; auditory canal; ear drum; cochlea

Explanation:

Sound waves enter the auditory canal (outer ear). They then hit the ear drum (tympanic membrane), causing it to vibrate. The vibrations are transmitted to the ossicles (malleus, incus, stapes - middle ear bones). Finally, the ossicles' vibrations are passed to the cochlea (inner ear, where sound is converted to neural signals).

Answer:

auditory canal; ear drum; ossicles; cochlea
