Across
  1. 5. Can cause infection of the cochlea & vestibular mechanism, and may result from permanent sensorineural hearing loss, vestibular dysfunction, & tinnitus
  2. 6. Primary site of localization of sound in space
  3. 8. Area that surrounds the core of the auditory cortex for auditory reception
  4. 9. What part of the malleus attaches to the tympanic membrane?
  5. 11. Resistance to the flow of energy
  6. 13. Minute cilia that protrudes from the upper surface of each hair cell, connected by thin tip links
  7. 14. Part of the auditory cortex that is divided into 3 portions and is responsible for primary reception of the auditory signal
  8. 15. Area responsible for doing spectral and temporal acoustic analyses of incoming sound information
  9. 17. What cranial nerve innervates the hair cells?
  10. 19. Forms the floor of the scala media, separating it from the scala tympani
  11. 20. Made up of 4 rows of hair cells that rest on a layer of Deiters’ cells for support
Down
  1. 1. Area of the thalamus that is the primary source of input to the core of the auditory cortex
  2. 2. The frequency to which the neuron responds best
  3. 3. A tool used for looking into the ear canal
  4. 4. The only way of getting oxygen (aeration) to the middle ear space; maintains equilibrium between the pressure of the middle ear and atmospheric pressure
  5. 7. Portion of the ear comprised of the ear canal and pinna
  6. 10. Has several functions: aid the localization of sound in space & capture sound energy
  7. 12. Area divided into two chambers, the scala vestibule & scala tympani
  8. 16. Helps to protect the tympanic membrane by trapping dirt and insects along with hair cells
  9. 18. A type of neural response to auditory stimulation; take longer to respond than other neurons; has initial on-response to high-intensity signal
