The helix (rim) and lobule (earlobe)
28
What is the typanic membrane (eardrum)?
A thin CT membrane that vibrates in response to sound
29
What is the middle ear
a small, airfilled, mucosa-lined cavity
30
Epitympanic recess
superior porrtion of middle ear
31
Pharyngotympanic tube
connects the middle ear to the nasopharynx
32
What 3 bones are contained in the typanic cavity?
malleus, incus, stapes
33
What does the bony labyrinth enclose?
encloses a membranous labrynth
34
What is the bony labyrinth filled with?
Perilymph
35
Membranous labyrinth
Serior of mebranous sacs within the bony labyrinth
36
What is the Membranou labyrinth filled with?
Potassium-rich fluid
37
What does the membranous labyrinth enclose?
Endolympth
38
Vestibule
The central egg-shaped cavity of the bony labyrinth
39
Suspended in the perilympth of the vestibule
saccule & cochlea
40
Location of maculae
In the vestibule
41
Receptor for audition
hair cell
42
Where does the utricle extend into?
semicircular canals
43
Maculae of the saccules
House equilibrium receptors
44
Membranous semicurcular ducts
lines the semicircular canals and communicates with the utricle
45
Ampulla
Swollen end of the semicurcular canals and houses equilibrium receptors
46
Where do ampullae keep equilibrium receptors?
Crista ampullaris
47
Equilibrium receptors respond to what?
Angular movements
48
What do the Corti have?
Has the hair cells that respond to hearing
49
Where is the organ of Corti held?
In the cochlea
50
3 chambers of the choclea
Scala vestiubli, cochlear duct, scala tympani
51
Scalas tympani and vestibuli contain what?
Perilymph
52
The cochlear duct contains what?
Endolymph
53
What is the floor of the cochlear duct composed of?
Bony spiral lamina
54
Basilar membrane
Supports the organ of corti by being the surface for the hair cells
55
The cochlear branch of the vestibulochlear nerve does what for the organ of Corti.
It connects the organ of Corti to the brain
56
The stereocilia (hair cells)
Protrude into the endolymph Touch the tecotrial membrane
57
Where do impulses from the cochlea go?
pass via the spiral ganglion to the cochlear nuclei
58
After impulses reach the cochlear nuclei, now what?
Superior olivary nucleus Inferior colliculus
59
After an impulse passes through the parts after the cochlear nuclei, what does it reach?
Auditory Cortex
60
What is pitch perceived by?
The primary auditory cortex and the cochlear nuclei
61
What is loudness perceived by?

What is localization perceived by?
Superior olivary nuclei
63
Conduction deafness
Sound conduction of the fluids of the inner ear are hampered with
64
Sensorineural deafness
Damage to the neural structures from the cochlear hair cells to the auditory cortex
65
Tinnitus
Ringing or clicking of the ears during absence of auditory stimuli
