100
This occurs when cochlear fluids are set into motion by vibrating the cochlear shell.
What is Bone Conduction
100
The names of the two types of hair cells of the inner ear are?
What are the Outer and Inner Hair Cells
100
This is a gelatinous membrane that the tallest outer hair cell cilia embed in.
What is the tectorial membrane
100
There are 3-5 rows of these
What are outer hair cells
100
The traveling wave always travels from ? to ?
What is base to apex
200
Is commonly caused by otosclerosis (a fixation of the stapes footplate) and affects bone conduction in the 2,000 Hertz frequency range.
What is Carhart's Notch
200
The cochlea is widest at this part
What is the base
200
This structure protects the hair cells from endolymph
What is the reticular lamina
200
This part of the hair cell is the only part that can regenerate
What are tip links
200
Otoacoustic emissions measure the presence or absence of what?
What are the outer hair cells
300
This component occurs when the stapes is not in "sync" with the cochlear shell. Happens most at 2,000 Hz.
What is the inertial lag
300
The scala vestibuli and scala tympani are filled with this fluid
What is perilymph
300
The basilar membrane is ? times wider at the ?
What is 5 and apex
300
When the cilia shear towards stria vascularis the tip links do what to the microchannels
What is open them
300
Which type of neurons attach to the inner hair cells, are bipolar, and are myelinated?
What are Type I Neurons
400
The way the skull moves and changes slope during sound stimulation is commonly known as?
What is compression/distortion
400
The scala vestibuli houses this window
What is the oval window
400
The inner hair cells are located near this structure
What is the modiolus
400
Outer hair cells sides contain this protein, whereas cilia is composed of this fiber
What are Prestin protein and actin fiber
400
This is a chamber in the osseospiral lamina where the nerve bodies cluster
What is the Rosenthal canal
500
When the cochlear shell is vibrating, but there is no stimulation of the mastoid bone or forehead.
What is bone conduction via air conduction
500
These are the holes in the bone of cochlea where nerve fibers exit
What are the habenulae perforata
500
The major supporting structure of the organ of Corti is this ? It is comprised of inner and outer pillar cells
What is the arch of Corti
500
This is the protein that allows the insertion plaque to move up or down on the cilia
What is myosin I
500
What potential is created when a neurotransmitter is absorbed and depolarizes the negative inside of a neuron
What is a generator potential
