Outer Ear Anatomy
The thin, concave, oval membrane that separates the outer and middle ear.
What is the tympanic membrane?
This part of the ear equalizes pressure.
What is eustachian tube?
The fluid that fills the cochlea.
This is the term for the energy loss as the auditory signal moves further from it's source.
What is impedance?
This part of the brain interprets the auditory signal.
What is cerebral cortex?
This part of the ear collects and shapes sound.
What is outer ear (pinna or EAM)?
The ossicle that connect to the TM.
What is the malleus?
The nerve that transmits auditory information.
What is the 8th cranial nerve.
This is the first site of binaural interaction.
What is superior olivary complex?
The scientific name for ear infection
What is otitis media?
The edge of the pinna.
What is the helix?
The middle ossicle.
What is the incus?
What is by frequency?
This is what we perceive frequency as.
What is pitch?
This type of hearing loss can benefit from hearing aids.
What is conductive?
The scientific name for earlobe.
What is lobule?
The ossicle that pushes on the oval window.
What is the stapes?
Respond to rotary movements.
What are semicircular canals?
What are hair cells?
This type of hearing loss is treated with cochlear implants.
What is sensorineural?
The part of the ear that sticks out next to the EAM.
What is tragus?
This is the middle of the tympanic membrane.
What is umbo?
Provides spectral analysis.
What is organ of corti?
These are the three way the ear does impedance matching.
What are TM and oval window area, TM buckling, and lever movement of ossicles?
Explain the auditory pathway.
Cochlea to cochler nerve to SOC to IC to SGB to Cerebral cortex
