- 8. The tiny fibers that connect individual hair cell stereocilia are called ____________.
- 11. The ___________ membrane extends from the spiral limbus out into the Scala media over the entire Organ of Corti, making contact with the tallest tips of the outer hair cell stereocilia.
- 13. __________ is the fluid located within the membranous labyrinth of the inner ear. This fluid is high in Potassium (K).
- 15. The three canals of the vestibular system which each contain a sense organ that responds to angular acceleration of the body.
- 16. The cochlear pattern of the membranous labyrinth that is filled with endolymph is called the ________________.
- 19. The single row of flask-shaped sensory cells in the Organ of Corti at the inner ear is called the ________________.
- 20. Cylindrically shaped cells in the Organ of Corti that are arranged in three rows along the length of the basilar membrane are the _____________.
Down
- 1. The _____________ is the sense organ of hearing.
- 2. The ___________ is a triangular-shaped support structure created by the inner and outer rods of Corti and located between the inner and outer hair cells.
- 3. ____________ membrane separates the scala media and the Scala tympani.
- 4. This is the vascular strip located on the lateral wall of the scala media.
- 5. The Organ of Corti resides in the ______________ membrane.
- 6. The __________ is the part of the inner ear that contains the sense organ hearing and where mechanical motions generated by sound are coded into nerve impulses for transmission to the CNS.
- 7. The spiral, corkscrew-shaped bony shelf that projects from the side of the modiolus and partially divides the cochlear tunnel into smaller sections is called the ____________.
- 9. The upper surface of the Organ of Corti formed by the tops of the hair cells and supporting cells is called the _______________.
- 10. The _________________ is the cavity that contains the inner ear and is located within the petrous portion of the temporal bone.
- 12. The ________________ is a narrow passage at the apex of the cochlea at which the scala tympani and scala vestibuli are connected.
- 14. ___________ is the fluid located within the bony labyrinth. It is high in Sodium (Na).
- 17. The central bony channel of the cochlea within which the spiral ganglia are located is the ___________.
- 18. The ________________ are the tiny hair-like projections from one end of a hair cell that are responsible for changing mechanical motions into electrochemical impulses that can be transmitted by the nervous system.
