Across
  1. 3. tiny opening at the apex of the cochlea where scala tympani and scala vestibuli connect
  2. 8. a perilymph- filled scala where the round window is located on
  3. 10. part of the inner ear that is 35mm long and turns 2 3/4 times
  4. 11. where the cochlea is located in the temporal bone
  5. 12. this fluid is high in sodium
  6. 13. hair cells that are cylindrical in shape and amount to 12000 in a human ear
  7. 15. hair cells that are flask-shaped and amount to 3500 in a human ear
  8. 16. the upper surface of the organ of Corti that is formed by the tops of hair cells and supporting cells.
  9. 17. one of the scala also known as the cochlear duct
  10. 19. this fluid is high in potassium
  11. 20. the bony core at the center of a cochlea
Down
  1. 1. this single cell layer membrane divides the scala vestibuli from the scala media
  2. 2. tiny hairs that project from the top of each hair cell
  3. 4. a triangular-shaped support structure created by the inner and outer pillars of Corti
  4. 5. divides the scala media from scala tympani and undergoes a wave motion
  5. 6. this structure serves as the battery of the ear, produces endolymph, and generates the cochlear potential
  6. 7. a spiral bundle that runs through the center of the modiolus
  7. 9. the organ of hearing located on the basilar membrane responsible for converting mechanical vibrations to neural impulses
  8. 14. spiral corkscrew bony shelf structure
  9. 18. a perilymph-filled scala where the oval window is located on
