Chapter 7
Across
- 4. chemical released by animals that affect the behavior of other animals within the same species
- 10. -membrane, also known as the eardrum, the point where sound waves strike after passing through the auditory canal
- 13. cortex where auditory information ultimately reaches
- 17. deafness People with this type of deafness have a normal cochlea and auditory nerve, and can hear their own voices clearly
- 18. auditory receptors that lie between the basilar membrane of the cochlea and the tectorial membrane
- 21. the theory that each frequency activates the hair cells at one place along the basilar membrane and the nervous system distinguishes among frequencies based on which neurons respond
- 23. where the vibrations of the tympanic membranes are transformed into waves of greater pressure
- 24. Latin name for the “hammer” middle ear bone
- 25. receptors on the surface of the tongue that can contain up to 10 taste buds
Down
- 1. the stimulation of one sense evokes the perception of another sense
- 2. theory saying the basilar membrane vibrates in synchrony with a sound, causing auditory nerve axons to produce action potentials at the same frequency
- 3. a set or receptors specialized to respond to pheromones
- 5. the sense of smell
- 6. frequent of constant ringing in ears
- 7. English name for the “incus” middle ear bone
- 8. three small fluid filled tubes that sense movement of the head and help maintain balance
- 9. detects sudden displacements or high frequency vibrations on the skin
- 11. the intensity of a sound wave
- 12. reduced response to one taste after exposure to another
- 14. receptors on the tongue
- 15. Latin name for the “stirrup” middle ear bone
- 16. a type of deafness that results from damage to the cochlea, hair cells, or auditory nerve, and can be inherited
- 17. chemical that makes peppers taste hot
- 19. the rate of compressions per second, measured in hertz
- 20. theory stating the spinal cord neurons receive messages from pain receptors also receive input from touch receptors and from axons descending from the brain
- 22. fluid filled spiral shaped structure of the inner ear
