100
the technical term for the visible part of the ear
What is the pinna
100
vibrations against this structure cause the ear bones to vibrate against the oval window
What is ear drum (tympanic membrane)
100
the structures that work in all 3 planes of dimension
What are the semicircular canals
100
the other sense that coordinates with equilibrium to tell you your place in space
What is vision
100
the bone that hits the oval window
What is the stapes
200
the "hearing" part of the inner ear
What is the cochlea
200
the structure that allows for free movement of sound waves through the liquid of the cochlea
What is the round window
200
the tiny rocks that sit on the gelatinous membrane
What are the otoliths
200
movement of this structure stimulates the movement of stereocilia in the semicircular canals
What is a cupula
200
the location in the cochlea that registers low-pitched sounds
What is the tip
300
the tube that connects the ear to the nasopharynx
What is the eustachian tube
300
the name of the cranial nerve that transmits sound and balance information to the brain
What is the vestibulocochlear nerve
300
the largest of a stereocilia group--stereocilia bend toward or away from this structure
What is the kinocilium
300
the rolling of these structures intensify the movement of the saccule and utricle
What are otoliths
300
the property of waves that accounts for "volume" of sounds
What is amplitude
400
the technical names of the 3 bones of the middle ear
What are the incus, malleus, and stapes
400
movement of sound waves across the basilar membrane causes these structures to bend, which in turn generates an electrical impulse
What are the stereocilia
400
controls horizontal gravitational equilibrium
What is the utricle
400
this event triggers the beginning of the nerve impulse
What is bending the stereocilia
400
in the cochlea, the stationary structure that stereocilia is embedded in
What is tectorial membrane
500
the names of the 3 chambers of the cochlea
What are the vestibular, tympanic, and cochlear
500
The location of the cochlea where high-pitched sounds are registered
What is base/lower end
500
gelatinous sac that controls rotational equilibrium
What is the cupula
500
this material causes swirling of the gel in the membrane and gives someone the spins
What is alcohol/ethanol
500
the part of the ear that controls gravitational equilibrium
What is the vestibule--saccule + utricle
