Which of the following serves as the function(s) of ear bones?
To transmit sound waves.
To transmit sound vibrations.
To amplify sound vibrations.
To provide support.
Middle ear is
filled with perilymph.
filled with endolymph.
filled with air.
Cochlea
is fluid-filled.
is a component of middle ear.
has sensory hair cells to detect sound vibrations.
has sensory hair cells to detect body movement.
Ear drum
separates outer ear from middle ear.
amplifies sound vibrations.
converts sound waves into sound vibrations.
is inelastic.
Hearing sensation is provided by
ear drum.
ear bones.
cochlea.
auditory centre of cerebral cortex.
Sensory hair cells in the cochlea
detect vibrations of endolymph caused by sound waves.
gives hearing sensation.
initiate nerve impulses upon stimulation.
serve as receptors.
If sensory hairs of ALL sensory hair cells are distorted,
his auditory centre of cerebral cortex will then be malfunctioned.
no sensory nerve impulses can be initiated by sensory hair cells.
no hearing sensation is provided.
sensory hair cells cannot be vibrated any more.
Eustachian tube
connects middle ear cavity with pharynx.
is fluid-filled.
is to equalize air pressure on two sides of the ear drum.
is blocked by valves.
Semicircular canals
have sensory hair cells to detect sound vibrations.
are fluid-filled.
are located at middle ear.
are responsible to detect change of position during movement.
