Across
  1. 2. Tube shaped cells that act as the ears amplifiers, physically stretching and shrinking to boost quiet sounds
  2. 3. The bottom fluid filled chamber that ends at the round window
  3. 7. Flask shaped cells that act as the ears main transmitters, responsible for sending 95% of all sound information to the brain
  4. 9. The floor of the scala media, supporting the Organ of Corti, moving like a wave with sound vibration
  5. 10. The top fluid filled chamber that sound vibrations enter
  6. 14. A corkscrew shaped bony projection that supports the cochlear chambers and membranes
  7. 16. A tiny opening at the apex of the cochlea where the Scala Vestibuli and Scala Tympani meet
  8. 17. The battery of the ear, producing potassium ions and endocochlear potential, located on the outside wall of the Scala Media
Down
  1. 1. The sensory organ of hearing, located in the Scala Media, that converts mechanical vibrations into nerve impulses
  2. 4. The narrow end of the cochlear spiral that vibrates best to low frequency sounds
  3. 5. High sodium fluid found in the scala vestibuli and the scala tympani
  4. 6. The widest part of the cochlear spiral that vibrates best in response to high frequency sounds
  5. 8. Tiny hairs on the top of the inner and outer hair cells that move back and forth, triggering hearing
  6. 11. A thin membrane separating the Scala Vestibuli from the Scala Media
  7. 12. The central bony core that the cochlea wraps around
  8. 13. High potassium fluid found in the Scala Media
  9. 15. The middle chamber of the cochlear spiral, also called the cochlear duct, which contains the organ of Corti
