[Campbell Biology P.1163] Which of the following sequences correctly describes the path of a ... | Practice Question

Which of the following sequences correctly describes the path of a sound wave's mechanical vibration as it is transduced in the ear, up to the point of creating fluid pressure waves in the cochlea?

  • A: Tympanic membrane → Middle ear bones → Oval window
  • B: Oval window → Tympanic membrane → Middle ear bones
  • C: Tympanic membrane → Oval window → Middle ear bones
  • D: Middle ear bones → Tympanic membrane → Oval window

Explanation

Sound waves cause the tympanic membrane to vibrate. These vibrations are then transmitted by the three bones of the middle ear to the oval window, which in turn creates pressure waves in the fluid inside the cochlea.
