Presentation Transcript

  1. Anatomy and Physiology of the Ear • Cross section • Pinna • Tympanic membrane (eardrum) • Ossicles • Inner ear • Cochlea

  2. Cross section

  3. Pinna

  4. Tympanic membrane (eardrum)

  5. Ossicles

  6. Inner ear

  7. Cochlea

  8. Physiology • How does the ear work? • Sound waves enter ear canal where they are amplified (resonated). • Tympanic membrane and ossicles vibrate. • Fluids of inner ear vibrate and stimulate hair cells. • Hair cells release an electric signal which travels to the brain.
