Anatomy of hearing

4. the thin membrane that separates the scala media and scala vestibuli
13. first bone of the middle ear, sometimes commonly called "the hammer"
14. the non-bony "floor" that the Organ of Corti rests on
16. the fluid that fills only the middle chamber of the cochlea
17. the portions of the vestibular system that allow us to feel rotational movement
18. the name for the three small bones of the middle ear
20. the area in which the hair cells are located, where the actual process of hearing takes place
23. a ridge of cartilage that forms the outer edge of the concha
25. the third bone of the middle ear, sometimes commonly called "the stirrup"
26. the bony shelf that spirals up the cochlea and forms part of the barrier between the scala media and scala tympani
27. the smallest muscle of the body, also involved in the auditory reflex, part of the middle ear

1. the portion of the outer ear that lacks cartilage
2. forms the boundary between the outer ear and middle ear
3. the second smallest muscle of the body, found in the middle ear, part of the auditory reflex
5. the uppermost chamber within the cochlea, which sound waves enter into first
6. the bowl shaped indentation that houses the EAM
7. the sensory organs within the vestibular system's semicircular canals
8. the boundary between the inner ear, specifically the cochlea, and the middle ear
9. the type of hair cell primarily responsible for amplifying certain ranges of frequencies
10. this section of the outer ear is approximately 2/3rds osseous and 1/3 cartilaginous
11. small flap of cartilage by the EAM
12. the fluid that fills the two of the chambers of the cochlea
15. the lowermost chamber within the cochlea
19. the middle chamber of the cochlea, which is not directly connected to the other two chambers
21. the type of hair cell primarily responsible for the actual sensation of hearing
22. the second bone of the middle ear, sometimes commonly called "the anvil"
24. forms the lateral outermost edge of the pinna or auricle
