Solution

The correct option is B Maintain equilibrium of the body
Semi -circular are part of internal ear, they are lined by cilia ( microscopic hair) and filled with endolymph, every time the head moves, the endolymph moves the cilia.this works as a type of motion sensor, as the movement of cilia are communicated to the brain. As a result , brain knows how to keep the body balanced regardless of the posture

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?

Q. Identify the sequence in which the sound vibrations reach the brain:

\begin{matrix} Parts & Function (a) External ear & (i) Amplifies the vibrations received on the tympanic membrane. (b) Middle Ear & (i i) Converts the vibrations into nerve impulses and sends them to brain. (c) Inner Ear & (i i i) Directs the sound waves towards the tympanic membrane. \end{matrix}

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