25
when the oval window vibrates, it causes the fluid in the cochlea to _
VIBRATE
26
the fluid that surounds a membrane running through the middle of the cochlea is called _
BASILAR MEMBRANE
27
the resting place of the organ corti
BASILAR MEMBRANE
28
contains the receptor for the sense of hearing
BASILAR MEMBRANE
29
when the _ membrane vibrates, it vibrates the organ corti, causing it to brush against a membrane above it
BASILAR MEMBRANE
30
special cell in the organ corti, which are the receptors for sound
HAIR CELLS
31
when these hair cells/auditory receptors are bent up against the other membrane, causes them to send a neural message through the _ nerve
AUDITORY NERVE
32
contains the axons of all the receptor neurons
AUDITORY NERVE
33
neural message sent to the auditory nerve and into the brain through the _
THALAMUS
34
hair cells bent, neural mesage to auditory nerve, brain through thalumus then the _ will interpret the sound
AUDITORY CORTEX
35
the transformation of the vibrations of sound into neural messages
TRANSDUCTION
36
louder sounds in the outside world = stronger vibrations, stimulate morehair cells which the brain interpret as _
LOUDNESS
37
refers to high or low sound, depends on where the hair cells that are stimulated are located on the organ corti
PITCH
38
developed by Ernest Rutherford 1886
FREQUENCY THEORY
39
the pitch is related to how fast the basilar membrane vibrates
FREQUENCY THEORY
40
the faster the basilar membrane vubrates = higher the pitch, slower vibratiion = lower pitch
FREQUENCY THEORY
41
this theory works for low pitches
FREQUENCY THEORY
42
this theory works for moderate to high pitches
PLACE THEORY
43
who developed frequency theory
ERNEST RUTHERFORD 1886
44
who developed the third theory called volley principle
ERNEST WEVER & CHARLES BRAY
45
theory that appears to account for pitches from 400Hz up to 4000Hz, which groups of auditory neurons are volleying
VOLLEY PRINCIPLE
46
a process which the groups of auditory neurons take turns firing
VOLLEYING
47
1.CONDUCTION HEARING IMPAIRMENT or CONDUCTIVE HEARING LOSS 2.NERVE HEARING IMPAIRMENT or SENSORINEURAL HEARING LOSS
TYPES OF. HEARING IMPAIRMENT
48
TERM USED TO REFER TO DIFFICULTIES IN HEARING
HEARING IMPAIRMENT
49
A PERSON CAN BE _ HEARING IMPAIRED OR _ HEARING IMPAIRED
PARTIALLY HEARING IMPAIRED, TOTALLY HEARING IMPAIRED
50
THE TREATMENT FOR HEARING LOSS WILL VARY ACCORDING TO THE _ FOR THE IMPAIRMENT
REASONS
51
REFERS TO PROBLEMS WITH THE MECHANICS OF THE OUTER OR MIDDLE EAR, SOUND VIBRATIONS CAN'T BE PASSED FROM THE EARDRUM TO COCHLEA
CONDUCTION HEARING IMPAIRMENT or CONDUCTIVE HEARING LOSS
52
THE CAUSE OF THIS IMPAIRMENT MIGHT BE DAMAGED EARDRUM OR DAMAGE TO THE BONES OF THE MIDDLE EAR, USUALLY FROM AN INFECTION
CONDUCTION HEARING IMPAIRMENT or CONDUCTIVE HEARING LOSS
53
IN THIS KIND OF IMPAIREMNT THE CAUSES CAN BE TREATED, USING A HEARING AIDS
CONDUCTION HEARING IMPAIRMENT or CONDUCTIVE HEARING LOSS
54
CAN BE USE IN RESTORING HEARING
HEARING AIDS
55
THE PROBLEM LIES EITHER IN THE INNER EAR OR IN THE AUDITORY PATHWAYS AND CORTICAL AREAS OF THE BRAIN
NERVE HEARING IMPAIRMENT or SENSORINEURAL HEARING LOSS
56
MOST COMMON TYPE OF PERMANENT HEARING LOSS
NERVE HEARING IMPAIRMENT or SENSORINEURAL HEARING LOSS
57
NORMAL _ CAUSES LOSS OF HAIR CELLS IN THE COCHLEA, AND EXPOSURE TO _ CAN DAMAGE HAIR CELLS
NORMAL AGING , LOUD NOISES
58
POSSIBLE CAUSES ARE NORMAL AGING AND EXPOSURE TO LOUD NOISES
NERVE HEARING IMPAIRMENT or SENSORINEURAL HEARING LOSS
59
COLLECTIVE NAME OF THE THREE TINY BONES IN THE MIDDLE EAR
OSSICLES
60
THE SMALLEST BONES IN THE HUMAN BODY
OSSICLES (HAMMER, ANVIL, STIRRUP
61
based on an idea proposed in 1863 by Hermann von Helmholtz and elaborated on and modified by Georg von Békésy, beginning with experiments first published in 1928
Place Theory
62
In this theory, the pitch a person hears depends on where the hair cells that are stimulated are located in the organ of the Corti.
Place Theory
63
WHO PROPOSED AND MODIFIED PLACE THEORY
Hermann von Helmholtz & Georg von Békésy,
