Do You Know Auditory System? Play This Quiz - Quiz

The auditory system is a body system that is responsible for the sense of hearing. The primary auditory cortex lies in the superior temporal gyrus of the temporal lobe and extends into the lateral sulcus and the transverse temporal gyri. Test out what else you know about the system through the questions below.

  Ossicular system
6.

What accounts for the amplification of sound vibrations in the middle ear?
- A.
  
  The decrease in surface area from the tympanic membrane to oval window
- B.
  
  The lever action of the ossicles
- C.
  
  The auricle of the ear
- D.
  
  The high sensitivity of the hair cells
- E.
  
  More than one of the above
7.

When exposed to loud/damaging sounds, what will manifest physically in the auditory system?
- A.
  
  Skewed basilar membrane
- B.
  
  Fractured ossicles
- C.
  
  Missing hair cells/scar tissue
8.

What protects the ear from loud, low frequency sounds?
- A.
  
  Tymapnic membrane deflecting these frequencies
- B.
  
  Contraction reflex of ossicular muscles
