Across
  1. 2. the entrance to the ear canal
  2. 4. these take longer to respond than other neurons and have an initial on-response for strong stimuli
  3. 8. the firing patterns that most resemble VIII nerve patterns
  4. 10. what we usually refer to as the ear
  5. 11. the ability of the cochlea to differentiate the spectral components of a signal
  6. 12. responses that do not appear related to stimulus frequency but have a periodic pattern as long as a tone is present
  7. 13. forms the floor of the scala media and separates the scala media and scala tympani
  8. 15. the largest of the ossicles that provides the point of attachment with the tympanic membrane
  9. 16. embedded in the petrous portion of the temporal bone and houses the inner ear structures
  10. 17. this muscle rotates the stapes posteriorly and is innervated by the facial nerve
  11. 18. this muscle pulls the malleus anteromedially and is innervated by the trigeminal nerve
Down
  1. 1. the smallest of the ossicles
  2. 2. the receptor organ for movement that is made up of of ciliated receptor cells and a supporting membrane
  3. 3. a composite of the responses of a single fiber at each frequency of presentation
  4. 5. the resistance to the flow of energy
  5. 6. marks the boundary between the outer and middle ear
  6. 7. this point of the basilar membrane determines the frequency information transmitted to the brain
  7. 9. the entryway to the cochlea
  8. 14. permits communication between between the scala vestibuli and the middle ear space
  9. 19. voltage potential differences that can be measured from the cochlea at rest
