Flashcards in Otology Deck (65):
1

ossicles

bones of the middle ear that carry sound vibrations.

2

labyrinth (inner ear)

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

3

cochle/o

cochlea

4

eustachian tube

connects the middle ear and the pharynx.

5

semicircular canals and vestibule

contains receptors and endolymph that help the body maintain its sense of balance

6

aur/i, aur/o, ot/o

ear

7

external ear auricle (pinna)

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

8

audi/o

hearing

9

otomastoiditis (o-to-mas-toyd-I-tis)

inflammation of the ear and the mastoid bone

10

labyrinthitis (lab-i-rin-THI-tis)

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

11

mastoiditis (mas-toyd-I-tis)

inflammation of the mastoid bone

12

myringitis (mir-in-JI-tis)

inflammation of the tympanic membrane (eardrum)

13

cochlea

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

14

labyrinth/o

labyrinth (inner ear)

15

mastoid boane and cells

located in the skull bone behind the external auditory canal

16

mastoid/o

mastoid bone

17

otalgia (o-TAL-ja)

pain in the ear

18

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

19

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

staped/o

stapes (middle ear bone)

21

myring/o

tympanic membrane (eardrum)
