Across
  1. 1. type 2 hair cells are located in what area?
  2. 3. located in the pons and medulla, made of the MVN, LVN, and IVN, there are 2 of them.
  3. 6. this canal is angled 20-30 degrees upward from the IAC
  4. 7. the enlarged area that contains the cupula and crista ampullaris
  5. 11. this is produced through the filtration of blood vessels
  6. 13. deflection of the hair cells towards the kinocilium
  7. 16. when this substance enters the hair cells, it causes depolarization and therefore causes the action potential to synapse with the nerve below
  8. 19. in the anterior and posterior canals, excitation is classified as ______.
  9. 22. the calcium carbonate crystals on the macula
  10. 25. type 1 hair cells are located in what area?
  11. 26. this is due to the striola dividing excitation as saccule excitation is away from the striola and utricle excitation is toward the striola
  12. 27. endolymph is produced by what kind of cells?
  13. 29. in the horizontal canal, excitation is classified as _____.
  14. 30. the tall singular vestibular stereocilia in back of the cell base
Down
  1. 2. communication between perilymph and CSF happens through which structure?
  2. 4. the central region that divides the macula into two directions of excitation, comprised of very tiny otoconia
  3. 5. Right anterior left posterior (ear, canal pairing)
  4. 8. the flocculus is also responsible for initiating the compensation process after the loss of a ______.
  5. 9. place of direct and indirect communication with vestibular nuclei
  6. 10. a gelatinous goblet shaped structure that serves as a barrier to the vestibule and is not responsive to gravity
  7. 12. the otolith organ that is in the horizontal plane and is more loosely adhered to the skull (33,000 HC)
  8. 14. the type 2 hair cells have what kind of ending?
  9. 15. The vestibular nerve with the horizontal canal, anterior canal, utricle, and a bit of the saccule
  10. 17. the covering of each otolith organ that, it contains calcium carbonate crystals, it DOES respond to linear acceleration (gravity/static position)
  11. 18. left anterior right posterior (ear, canal pairing)
  12. 20. the vestibular nerve with the posterior canal and saccule
  13. 21. the otolith organ that is in the vertical plane, therefore is more adhered to the skull (18,000 HC)
  14. 23. the location of the hair cells
  15. 24. defection of the hair cells away from the kinocilium
  16. 28. the type 1 hair cells have what kind of ending?
