Across 4. Measurement of amplitude of a sound wave is measured in ______ 5. Opening between the middle and inner ears 8. Boundary between the outer and middle ears which vibrates which hits by sound waves 10. Set of sacs containing balance receptors 11. Series of three tubes containing balance receptors 16. The number of sound waves in a given point of time 17. Tube connecting the middle ear to the throat, functioning to equalize pressure in the ear 18. Cartilaginous ear flap which functions to collect sound waves 19. Type of equilibrium which maintains position in response to sudden movement 20. As vibrations move into the inner ear, they become ______ because the oval window is smaller than the tympanic membrane 21. Vibration of the ______ causes the membrane over the oval window to vibrate 22. Structure within the bony labyrinth, containing hearing receptors 23. Tubes within the semicircular canals, containing fluid used to determine body position

Down 1. Type of equilibrium which maintains position in relation to gravity 2. System of sacs within the bony labyrinth, containing balance and hearing receptors 3. Series of cavities within the temporal bone 5. Three small bones which transfer vibration from external to inner ear 6. Special sebaceous glands which secret earwax 7. Measurement of frequency of a sound wave is measured in ______ 9. Vibrations in the fluid of the inner ear, cause bending of the ______, which stimulates action potentials 11. Organs which contain receptors for both static and dynamic equilibrium 12. The height of a sound wave 13. Muscle limiting movement of the stapes 14. Opening underneath the oval window, covered by a second tympanic membrane 15. Muscle limiting movement of the eardrum
