This Noise
100
This is a shell-shaped structure formed by elastic cartilage that funnels vibrations to the external auditory canal.
Auricle/pinna
100
This is a passage leading from the auricle, through the temporal bone, to the tympanic membrane.
External auditory canal (meatus)
100
This separates the external auditory canal from the tympanic cavity and transfers vibrations to the auditory ossicles.
Tympanic membrane (eardrum)
100
This passageway to the nasopharynx functions to equalize pressure between the middle and outer ear.
Pharyngotympanic (auditory) tube
100
This is a coiled, snail-shell-like organ that is used for hearing that arises from the vestibule.
Cochlea
200
This is the beginning of the inner ear, is connected to the stapes and transfers vibrations to the cochlea.
Oval window
200
This is found at the end of the cochlea acting as a pressure relief.
Round window
200
This is one of the auditory ossicles that is found between the malleus and stapes.
Incus (anvil)
200
DAILY DOUBLE! -- This labyrinth is housed in the temporal bone passageway. It also carries the _____ labyrinth within it. (Have two answers)
Bony labyrinth (in temporal bone passageway)
Membranous labyrinth (in bony labyrinth)
200
This is one of the auditory ossicles that is found between the incus and oval window. It is connected to the stapedius muscle.
Stapes (stirrup)
300
This is one of the auditory ossicles that is found between the tympanic membrane and incus. It is connected to the tensor tympani muscle.
Malleus (hammer)
300
This pulls the malleus away from the eardrum.
Tensor tympani
300
DAILY DOUBLE! -- This is a feather-shaped gelatinous substance that acts to open channels for depolarization. It is also part of what structure that converts vibrations to neural impulses?
Tectorial membrane (feather-shaped gelatinous substance)
Spiral organ of corti (converts vibrations to neural impulses)
300
This reduces the motion of the stapes to lessen the effect on the inner ear.
Stapedius
300
This fluid is helps to cushion and is found between the temporal bone passageways.
Perilymph
400
This is the portion of the vestibule that leads to the cochlea.
Saccule
400
This is the portion of the vestibule that leads to the semicircular canals.
Utricle
400
This separates the scala vestibuli from the cochlear duct.
Vestibular membrane
400
This separates the cochlear duct from the scala tympani.
Basilar membrane
400
This fluid is found within the membranous labyrinth that is house within the bony labyrinth.
Endolymph
500
These are equilibrium receptors found in the vestibule (saccule and utricle) that respond to the gravitational pull and changes in head position (specifically for static equilibrium).
Maculae
500
This is made up of anterior, posterior, and lateral ducts that respond to angular movements of the head (specifically for dynamic equilibrium).
Semicircular canal
500
This is filled with perilymph and begins near the oval window.
Scala vestibuli
500
This is filled with perilymph and ends at the round window.
Scala tympani
500
This is also called the cochlear duct and is filled with endolymph. It also contains the spiral organ of corti.
