  • Eardrum

Question 12

Question
The malleus, incus and stapes are small bones
Answer

Question
The fact that the various parts of the basilar membrane are tightly bound together is problematic for which of the following?
Answer
  • Both the frequency theory and the place theory
  • The place theory
  • Then volley theory
  • The frequency theory

Question 14

Question
People with massive damage to the primary auditory cortex:
Answer
  • Can no longer hear and recognise simple sounds
  • Are rendered deaf to only high-frequency sounds
  • Cannot reorganise combinations or sequences of sounds
  • Are rendered completely deaf

Question 15

Question
Conductive deafness is also known as:
Answer
  • An outer ear deafness
  • Middle ear deafness
  • Inner ear deafness
  • Nerve deafness

Question 16

Question
Damage to part of the cochlea that sends information about high frequency sounds to the primary auditory cortex could result in:
Answer
  • Complete hearing loss
  • Inability to hear sounds
  • Tinnitus
  • Hearing loss in the opposite ear

Question 17

Question
A sound shadow refers to:
Answer
  • How much louder a high-frequency sound is for the ear closest to the sound
  • In phase sound waves
  • The time it takes sound waves to reach the ear
  • Out of phase sound waves

Question 18

Question
In the otoliths organs, the otoliths are calcium carbonate particles that:
Answer
  • Enhance sound localisation
  • Vibrate with different frequencies
  • Stabilise the semicircular canals
  • Push against hair cells when moved

Question 19

Question
The function of the semicircular canals is to:
Answer
  • Establish a sense of direction whilst travelling
  • Locate the source of high frequency tones
  • Detect movement of the head
  • Locate the source of low frequency tones

Question 20

Question
Endorphins
Answer
  • Are human-made drugs which mimic endorphins
  • Have chemical structures just like morphine
  • Increase pain
  • Can interact with the same receptors as morphine

Question 21

Question
Which of the following is true according to the law of specific nerve energies?
Answer
  • Any stimulation of the auditory nerve is perceived as sound
  • A single nerve can convey either auditory or visual information
  • Each sensory system as a unique electrical charge
  • If one sensory system becomes inactive, others will compensate

Question 22

Question
What is the name of the receptor cells of the auditory system?
Answer
  • Rods and cones
  • Sound bulbs
  • Hair cells
  • Basilar membranes

Question 23

Question
Perception of low tone is to _____ as perception of high tone is to _____.
Answer
  • Volley principle; frequency theory.
  • Frequency theory; place theory
  • Place theory; volley principle
  • Gate theory; frequency theory

Question 24

Question
What is the major problem for the frequency theory of sound perception?
Answer
  • It cannot account for the perception of low pitch sounds
  • It cannot account for the perception of low amplitude sounds
  • It requires the cochlea to vibrate, but it does not
  • Neurons cannot respond as quickly as the theory requires

Question 25

Question
The frequency theory of pitch perception works well for _____ frequencies, while the place theory works well for the perception of _____ frequencies
Answer
  • Low; low
  • High; low
  • High; high
  • Low; high

Question 26

Question
High frequency tones produce maximum displacement
Answer
  • At the base of the basilar membrane
  • At the apex of the basilar membrane
  • In the middle of the basilar membrane
  • Across the entire length of the basilar membrane

Question 27

Question
To what lobe of the cerebral cortex is auditory information sent?
Answer
  • Occipital
  • Temporal
  • Parietal
  • Frontal
