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