bony spaces within the temporal bone of the skull. It contains the cochlea, semicircular canals, and vestibule.

3
Otology

cochle/o

cochlea

4
Otology

eustachian tube

connects the middle ear and the pharynx.

5

6
Otology

aur/i, aur/o, ot/o

ear

7
Otology

external ear auricle (pinna)

external structure located on both sides of the head. The auricle directs sound waves into the external auditory canal.

8
Otology

audi/o

hearing

9
Otology

inflammation of the labyrinth (inner ear, also called vestibular neuritis)

11
Otology

mastoiditis (mas-toyd-I-tis)

inflammation of the mastoid bone

12
Otology

myringitis (mir-in-JI-tis)

inflammation of the tympanic membrane (eardrum)

13
Otology

cochlea

is snail-shaped and contains the organ of hearing. The cochlea connects to the oval window in the middle ear.

17
Otology

otalgia (o-TAL-ja)

pain in the ear

18
Otology

tympanic membrane (eardrum)

semitransparent membrane that seperates the external auditory canal and the middle ear cavity. It transmitts sound vibrationsto the ossicles

19
Otology

external auditory canal (meatus)

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

20
Otology

staped/o

stapes (middle ear bone)

21

otosclerosis (o-to-skle-RO-sis)

hardening of the ear

28
Otology

acoustic neuroma (a-KOOS-tik nu-RO-ma)

benign tumor within the internal auditory canal growing from the acoustic nerve may cause hearing loss and may damage stuctures of the cerrebellum as it grows

29
Otology

ceruminome (se-roo-mi-NO-ma)

tumor of a gland that secretes earwax

30
