Auditory Nerve – HEARING TEST 4
The key terms of Hearing test 4 include, Auditory Nerve.
Where does the auditory nerve first pass through?
Enters brainstem at the cerebello pontine angle
Order that the nerve fibers pass through the cans
CN
SOC via lateral lemniscus
Inferior Colliculus
medial geniculate body
auditory cortex
How are the CANS organized and what does this mean
Tonotopically
cells responsive to diff freq are found in diff places at each level of CANS
Fibers from the base are on the ____ while fibers from the apex are on the ____
Outside
inside
APD
Auditory processing disorder
when people complain about not being able to hear speech in noise
HHIA
Hearing handicap inventory for adult
when it’s really high the it’s predictive of auditory processing disorder
Where is there cross over with bilateral info
SOC
Erber’s model of auditory skill development
Awareness/detection (hearing aids or cochlear implants)
discrimination
identification
comprehension
What happens to SNR in the words in noise tests?
SNR gets smaller
Tectorial membrane drapes over what
Organ of corti
Scala tympani starts where and what fluid
Round window
Periymph
Ototoxcity – 5 categories
Medications that cause damage to chochlea/vestib system
aminoglycosides
chemotherapy drugs
loop diuretics
salicylates
anti-malarial drugs
Nerve fibers of the CANS
Go from bottom of organ of corti into modiolus
form bundle of fibers which is the auditory nerve/cochlear nerve
