1
Q
ear
A
organ of hearing and balance; includes the external ear, middle ear, and labyrinth or inner ear
2
Q
external ear
A
consists of the auricle and external auditory canal (meatus)
3
Q
auricle
A
external, visble part of the ear; directs soundwaves into the external auditory canal
4
Q
external auditory canal
A
short tube that ends at the tympanic membrane. the inner part lies within the temporal bone of the skull and contains the glands that secrete earwax
5
Q
middle ear
A
consists of the tympanic membrane and the tympanic cavity containg ossicles
6
Q
tympanic membrane
A
semitransparent membrane that separates the external auditory canal and the middle ear cavity. the tympanic membrane transmits sound vibrations to the ossicles
7
Q
ossicles
A
bones of the middle ear that carry sound vibrations. the ossicles are made of malleus, incus, and stapes. the stapes connect to the oval window which transmits the sound vibrations to the cochlea of the inner ear
8
Q
eustachian tube
A
passage between the middle ear and the pharynx; equalizes air pressure on both sides of the tympanic membrane
9
Q
inner ear
A
consists of the labyrinth and connectors of the vestibular and cochlear nerves
10
Q
labyrinth
A
bony spaces w/in the temporal bone of the skull made up of 3 distinct parts, the cochlea, the semicircular canals, and the vestibule. the cochlea facilitates hearing.
11
Q
cochlea
A
coiled portion of the inner ear containing the sensory organ for hearing; connects to the oval window in the middle ear
12
Q
semicircular canals and vestibule
A
sensory organs of balance; contain receptors and endolymph that provide sensory information about the body’s position to maintain equilibrium
13
Q
vestibulocochlear nerves
A
paired cranial nerves responsible for hearing and balance; composed of vestibular fibers and cochlear fibers
14
Q
vestibular nerve
A
conveys information about position and balance from the semicircular canals and vestibule to the brain
15
Q
cochlear nerve
A
conveys information about sound, including volume and frequency from the cochlea to the brain
16
Q
