Across
  1. 2. The entrance to the ear canal
  2. 7. Excitation of the inner hair cells occurs primarily as a result of this effect on the cilia
  3. 9. This separates the outer and inner hair cells
  4. 10. The “stirrup;” one of the bones of the ear
  5. 11. These neurons slowly increase their firing rate through the initial stages of firing
  6. 13. Houses the sensors for balance and hearing
  7. 15. The curled margin of the pinna
  8. 18. This marks the boundary between the outer and middle ear
  9. 19. The bones of the ear are collectively known as this
  10. 20. In this type of response, there is an initial response to the start of a stimulus followed by silence
Down
  1. 1. of light This area that reflects the lights of an audiologist’s otoscope
  2. 3. This type of response does not seem to be related to stimulus frequency, but appear to have a periodic, chopped temporal pattern as long as a tone is present
  3. 4. Inflammation of the mastoid bone
  4. 5. This receives bilateral innervation from the LSO, as well as indirect input from the CN via the lateral lemniscus
  5. 6. This is lateral to the belt and makes up the third level of processing of the input auditory signal at the reception area
  6. 8. This receives input primarily from the contralateral ear via the ipsilateral MGB
  7. 12. These take longer to respond than other neurons, having an initial on-response for strong stimuli
  8. 14. Resistance to the flow of energy
  9. 16. The rate of firing increases because this increases
  10. 17. A device used to view cavities of the body
