Cochlea is responsible for what?

hearing!

Fluids in the cochlea convert waves into a message that travels to the brain stem via the what?? (p. 18)

Back 8

Auditory nerve

Front 9

True or False?
How is brain stem is connected to highest auditory center in the cortex? (p. 18)

Back 9

By a series of waystations that recieve, analyze and transmit impulses along the auditory pathway

Front 10

How do audiologists separate the ear?

Back 10

Conductive portion and sensory/neural portion

Front 11

What does the conductive portion consist of? (p. 18)

Back 11

outer and middle ears

Front 12

Sensory/neural portion consists of what?

Back 12

inner ear and auditory nerve

Front 13

Any sound that courses through the outer ear, middle ear, inner ear and infinity and beyond is heard by what?

Back 13

air conduction

Front 14

How is sound heard by bone conduction?

Back 14

Bypassing outer and middle ears by vibrating the skull mechanically and stimulating the inner ear directly

Front 15

Air conduction depends on functioning of what? (p.20)

Back 15

outer, middle and inner ear and neural pathways and beyond

Front 16

Hearing by bone conduction depends on functioning of what?

Back 16

Inner ear and infinity and beyond

Front 17

The impaired air conduction with normal bone conduction is known as what? (p.20)

Back 17

Conductive hearing loss

Front 18

Sensory/neural hearing loss is determined when what happens? (p. 20)

Back 18

When a hearing loss exists in which there is the same amount of attenuation for both air conduction and bone conduction

Front 19

True or False? Conductive hearing loss can be as bad as sensory/neural hearing loss (p. 20)

Back 19

True

Front 20

Malingering (p. 21)

Back 20

faking hearing loss

Front 21

Psychogenic hearing loss (p. 21)

Back 21

psychological disorder whose manifested in the symptom of hearing loss

Front 22

The Schwabach test is what kind of test?

Back 22

Bone conduction

Front 23

What is the mastoid process and how is it used in a bone conduction test? (p.23)

Back 23

Bony protrusion behind ear where tuning fork is set into vibration

Front 24

Interpretation of the Schwabach test results is difficult interpret in cases of what type of hearing loss? (p.23)

Back 24

Mixed hearing loss

Front 25

Why is it hard to interpret mixed hearing loss with the Schwabach test? (p.24)

Back 25

Because both the inner ears are very close together and embedded in the bones of the skull

Front 26

Performance of the Rinne test compares what? (p. 24)

Back 26

The patients' hearing sensitvity by bone conduction to their sensitivity to air conduction

Front 27

What kind of air conduction is a more efficient means of sound transmission to the inner ear?

Back 27

air conduction

Front 28

What is a positive Rinne? (p. 24)

Back 28

When people with normal hearing hear tuning fork sound best next to their ear

Front 29

Describe a negative Rinne test (p. 24)

Back 29

When people hear sound better BEHIND the ear

Front 30

Why does a false negative occur? (p. 24)

Back 30

Because their bone conduction is normal. They will hear a louder tone with the stem of the fork behind the ear.

Front 31

Describe the occlusion effect (p. 24)

Back 31

When those with normal hearing close off the opening into the ear canal and the loudness increases

Front 32

The occlusion effect is observed primarily with what type of sounds? (p.24)

Back 32

low pitched sounds

Front 33

The occlusion effect is evident in patients with what type of hearing loss? Which types of hearing loss is it not evident in?

Back 33

Evident in sensory/neural hearing loss
Not evident in conductive hearing loss

Front 34

Bing Test (p. 25)

Back 34

Normal hearers and those with sensory/neural hearing loss can hear pulsating sound when they open and close opening into hearing canal (conductive cannot hear this)
