Q

Middle third of the outer ear

A

Bony section of the temporal bone

21
Q

Inner third of the outer ear

A

Isthmus is a narrow opening

22
Q

What are the three occicles of the middle ear?

A

Malleus, incus, and stapes

23
Q

What does the Eustachian tube do?

A

Drains fluid from middle ear when opened; articulates to nasal cavity

24
Q

Muscles of the middle ear

A

Stapedeus = stapes

Tensor typani = malleus

25
Q

Which cranial nerve runs through the middle ear?

A

CN VII

26
Q

Perilymph fluid of inner ear

A

Fills bony labyrinth

27
Q

Endolymph fluid of inner ear

A

Fills cochlear duct/ membrane

28
Q

Which cranial nerve runs through the modiolus/ helicatrema

A

CN VIII- acoustic/ auditory nerve

29
Q

What do the semicircular canals do?

A

Sensory organs for balancing, propriception, and movement

30
Q

Where is the organ of Corti?

A

Found on basilar membrane (floor of cochlear duct)

31
Q

What is the cilia and what receptor does it have?

A
  • inner and outer hair cells

- mechanicoreceptors

32
Q

Afferent

A
  • Cochlear and vestibular ducts translate movement of cilia to CN VIII
  • sensory input to brain
  • hearing and balance/ movement
33
Q

Efferent

A
  • CV VIII also sends signal to cochlea and vestibular organs

- cilia stiffen to attenuate movement

34
Q

Eating and sound organs constitute a ______________ of sound energy

A

Transducer

35
Q

What is the auditory mechanism frequency range?

A

Around 10 octaves spanning 20-20,000Hz

36
Q

What are the 3 impedance matching mechanisms that equal a gain of 31 dB?

A
  • area ration provides a 25 dB gain
  • level advantage provides a 2 dB gain
  • bucking of TM provides a 4-6 dB gain
37
Q

What does the inner ear do?

A

Performs frequency and temporal acoustic of incoming acoustical signal

38
Q

Basilar membrane shape is affected by…?

A

Frequency and intensity

39
Q

What causes excitation of outer hair cells? Inner hair cells?

A
  • shearing effect on cilia

- fluid flow and endolymph turbulence

40
Q

Action potential

A

Electrical reaction resulting from difference in hair and endolymph electrical charges

41
Q

The frequency to which a neuron responds best

A

Characteristic frequency

42
Q

When can we not perceive differences in pitch?

A

At increments below 5%

43
Q

Core in the Heschl’s gyrus

A
  • primary auditory area on brain

- receives input directly from medial geniculate

44
Q

Belt in the Heschl’s gyrus

A
  • seems responsive to sound in space

- associated with somatosensory input and frontal visual process

45
Q

Parabelt in the Heschl’s gyrus

A

Integrated sound with visual input

46
Q

What decodes pitch/ loudness and timing of sound?

A

Dorsal superior temporal gyrus (core)

47
Q

Where are sounds integrated with phonological system?

A

Superior temporal sulcus

48
Q

What is benign paroxysmal positional vertigo and how is it treated?

A
  • provides patient with spinning perception that occurs suddenly relative to body position
  • treated by epley maneuver by moving the crystals from the ampulla to the vestibule
