The ear is divided into three parts:
external, middle, and inner ear
external and middle ear structures are involved in ________
hearing only
inner ear functions
equilibrium and hearing
what receptors are found in inner ear
mechanoreceptors
auricle (pinna)
shell-shaped external portion of the ear that collects and directs sound waves into
auditory canal
external acoustic meatus (auditory canal)
Short, curved tube lined with skin bearing hairs, sebaceous glands, and ceruminous
glands
auditory canal ends medially at the ______
tympanic eardrum
Medical term for Tympanic membrane is
myringes
Middle ear (tympanic cavity)
small, air-filled, mucosa-lined cavity within the temporal bone
Tympanic cavity is flanked laterally by _____ and mediappy by a bony wall with 2
openings called ____ and ____
tympanic membrane, oval & round window
tympanic vibrations are transmitted to three auditory bones/ossicles
Malleus (hammer) -lateral
Incus (anvil) -middle
Stapes( stirrup) – medial
function of middle ear
amplification of sound
Vibrations from tympanic membrane move through what process toward the
inner ear?
malleus --> incus --> stapes --> oval window
pharyngotympanic (auditory) tube
connects tympanic cavity to nasopharynx; equalizes middle ear pressure with outside
air by permitting air to enter or leave
another word for inner ear
bony labyrinth
inner ear is lined with a membrane called the
membranous labyrinth
perilymph
is the plasma-like fluid in the membranous labyrinth between the bone and membrane
