Across
  1. 1. When presented with low-intensity sounds, these stimulate the IHCs by displacing fluids in the subtectorial space
  2. 4. Do not require assistance from OHCs when presented with high-intensity sounds
  3. 7. This lamina rests on top of hair cell bodies
  4. 8. Inhibitory phase of the acoustic waveform that causes the TM to go in, the stapes footplate to go in, the BM to go down, and the round window to go in
  5. 9. Excitatory phase of the acoustic waveform that causes the TM to go out, the stapes footplate to go out, the BM to go up, and the round window to go out
  6. 10. Determined by how much the stapes is moving
  7. 12. Opposite of impedance
  8. 13. Testing at this intensity leads to broader tuning curves
  9. 14. Battery that helps ions move
  10. 16. Hair cell tip links deflect towards kinocilia
  11. 18. Action potential that originates from the spiral ganglion cells of the auditory nerve
  12. 19. Fluid displaced in Scala Vestibuli
Down
  1. 2. These move in the opposite direction of HC bodies
  2. 3. Determined by stapes speed
  3. 5. Motor protein that helps OHCs move
  4. 6. This plays a significant role in BM fine-tuning and reverse transduction
  5. 11. Hair cell tip links that deflect away from kinocilia
  6. 15. These curves are the visual depiction of frequency selectivity of the cochlea
  7. 16. Fluid with high K+ concentration, but low Na+ concentration
  8. 17. The physical characteristics of this membrane affect the speed and the amplitude of the traveling wave
