Q

How the ear works

A
  1. Sound waves enter the ear
  2. They strike the tympanic membrane
  3. Stapes vibrates the oval window
  4. Vibrations enter cochlea (which vibrates it’s basilar membrane)
  5. These vibrations bend hair cells and convert to electrical impulses which travel to the brain via cranial nerve 8
