sense organs (ear) Flashcards
the part of the internal ear related to the static balance of the body
eardrum
why do throat infection lead to ear infections
because the eustachian tube connects the middle ear with the throat, so infection can be passed
we should not put sharp objects into the ear
it may harm the eardrum and can cause a great loss to us
what is the location of the malleus
the malleus is located between the tympanic membrane and the incus
what surrounds the organs of Corti
endolymph
why is deafness caused
it is caused due to the rupturing of the eardrum/tympanum
what is the location of the semicircular canals
inner ear / membranous labyrinth/part of the inner ear arranged at 90 degrees to each other
what is the main function of the eustachian tube
equalizes air pressure on either side of the eardrum for it to vibrate freely
mention the exact location of the organ of Corti
on the basilar membrane of the cochlea
or
in the cochlea
what is the function of the ear ossicles
amplifies the sound vibration received by the tympanum and transmit it to the inner ear (cochlea)
name the ear ossicle which is attached to the tympanum
malleus/hammer
what does the auditory nerve do
transmits impulses from the ear to the brain
what is the exact location of the incus
found in the middle ear between malleus and stapes
what is the function of the eustachian tube
balances the air pressure on either side of the eardrum.
the exact location of the pinna
it is located in the external ear
