The part of the ear that transmits sound vibrations to the brain is the
(a) cochlea.
(b) stirrup.
(c) eardrum.
(d) auditory nerve.

Q. 1.The ears are fragile instruments.
A. These impulses travel via the auditory nerve to the brain, where they are interpreted as, say, words, music or an approaching vehicle.
B. When sound waves enter the ear, they cause the eardrum to vibrate.
C. These, in turn, stimulate auditory nerve fibers, each attuned to a different frequency.
D. The vibrations are transmitted to the cochlea, in the inner ear, where fluid carries them to neatly organized rows of hair cells.
6. Damage to this delicate apparatus results from both volume and length of exposure to sound.

Q. Three small interlocking bones: the hammer, the anvil, and the stirrup transmit the vibrations of the eardrum to the inner ear.

Q. Put these terms, which describe the way sound travels from the air through your ear, in the correct sequence:
three tiny bones in the middle ear vibrate;your outer ear catches the sound and moves it inside your ear; a special nerve carries messages about sound to your brain; your eardrum begins to vibrate; liquid in the coiled tube of your inner ear vibrates

Q. Cochlea contains that translates sound vibrations to nerve impulses

Q. Following is a list of the events (in a random order) that lead to the formation of an auditory impulse.
(i) Vibration is transferred from the malleus to the incus to the stapes.
(ii) Basilar membrane moves up and down.
(iii) Nerve impulse is transmitted in cochlear nerve to auditory cortex of brain for impulse analysis and recognitions.
(iv) Sound waves pass through ear canal.
(v) Stereocilia of hair cells of organ of Corti rub against tectorial membrane.
(vi) Sound waves cause ear drum to vibrate.
(vii) Nerve impulse is generated.
(viii) Vibrations move from fluid of vestibular canal to the fluid of tympanic canal.
(viii) Vibrations move from fluid of vestibular canal to the fluid of tympanic canal.
(ix) Membrane at oval window vibrates.
Which of the following options represents these events in a correct order?
