Question | Answer |
state structures of outer ear and function of each | Pinna or Auricle (first part of the outer ear) collects sound waves; auditory meatus: the opening the sound waves enter through; auditory canal |
state structures of middle ear and function of each | tympanic membrane (myringo) vibrate in response to sound waves causes three little bones to move; ossicles (tiny bones) - malleus, incus, stapes |
state structures of inner ear and function of each | oval window, round window,vestibule, cochlea, organ of corti hearing,semi circular canal, utricle, saccule for balance and equilibrium |
state structures lined with ceruminous glands and function of cerumen | auditory canal filter the air of pollutants |
state function of eustachian tube with reference to tympanic membrane | maintain proper pressure in middle ear connects middle ear to throat |
which structures are responsible for maintenance of equilibrium ?where? | semicircular canal utricle, saccule - inner ear |
hearing occurs in the | temporal lobes |
the nerve impulse is carried to the hearing centers of the brain by the | cochlear nerve |
the cochlear nerve is also referred to as | ace cranial nerves, auditory nerve, acoustic nerve |
other than hearing, the ear also assist the body in maintaining | balance |
the function of balance is performed in knee | semi-circular canals, utricle, saccule |
the three chambers of the ear Rd | outer, middle, and inner chambers |
the outer ear consists of the | pinna also known as the Oracle |
the pinna collects sound waves and carries them to the | auditory meatus |
the auditory meatus is the opening into the | auditory canal |
the auditory canal is lined with | ceruminous glands and cilia which is real hair |
this ceruminous glands and silly cilia in the auditory canal serve to: | protect the auditory canal and filter the air entering at this point |
the structure beginning the middle ear is termed the | tympanic membrane or my Ringo |
what happens as the sound waves hit the eardrum or tympanic membrane? | It vibrates in response |
what does the vibration of the tympanic membrane caused | movement of the ossicles |
where are the ossicles located? | second structure in the middle ear |
what are the names of the ossicles? | Malleus, incus, stapes |
what does the movement of the ossicles cause? | the In and Out fluctuation of the oval window which is the first structure of the inner ear |
in the inner ear, the initial area just after the oval window is termed the | vestibule |
the vestibule leads into the | cochlea |
the cochlea is a | snail like structure that is filled with auditory fluids |
at the base of the cochlea we find the structure termed | the organ of Corti which is often described as the organ of hearing |
in the organ of Corti there are microscopic | cilia like structures which are stimulated by a wave like movement of the auditory fluid |
the stimulation of the cilia like structures caused by the wave like motion converts into | a nerve impulse |
what are located in the inner ear and assist in the maintenance of the body's equilibrium? | The semi circular canalS, utricle, saccule |
the tympanic membrane should of here up here appear | shiny, grey or beige in appearance |
when the tympanic membrane is red or pink it is an indication of | infection |
when the tympanic membrane appears dull it is an indication | fluid behind the ear |
the examination of the ear is performed with an instrument termed | an otoscope |
the specialist to examine the ear is called an | ENT |
trace sound waves from pinna to temporal lobe of the brain | pinna (Auricle), meatus, auditory canal, tympanic membrane (myringo), auditory ossicles, Oval window, round window, vestibule, cochlea, organ of corti, cochlear nerve, temporal lobes |
what is the smallest bone in the body | Stapes |
define tinnitus | ringing in the ears |
define vertigo | lack of balance causes dizziness |
define anacusis | lack of hearing |
define presbycusis | loss of hearing acuity due to aging |
define otosclerosis | hardening of the shtepise gradual |
define Meniere's syndrome | volume of auditory fluid too high, cause unknown, abnormal stimulation |
define auditory agnosia | hearing is just fine but no comprehension of what you hear |
what can cause auditory agnosia | trauma, closed head injury, stroke |
describe the appearance of a normal ear drums | shiny, beige |
describe the appearance of an ear drum that is infected | red or pink |
describe the appearance of an eardrum with fluid behind it | dull |
define decibels | volume |
what is the range of decibels humans can hear? | 20- 20,000 decibels |
define frequency | pitch,how high or low a sound might be |
define helix | folded portion of the pinna |
define otalgia | earache or ear pain |
define tympanotomy with tubes/myringotomy | incision in eardrum with tubes to relieve fluid buildup and pressure in the ear |
what group is most likely to need a tympanotomy with tubes? | Young children |
why do young children need a tympanotomy with tubes? | Because their eustachian tube is shorter and more horizontal |
the vestibular nerve leads to the brain from the | semi-circular canals |
the vestibular nerve is responsible for | equilibrium |
