The ossicles (middle ear bones) amplify sound approximately - ANSWER 30 fold
Which of the following canals is NOT found in the cochlea (according to your text)? -
ANSWER semicircular canal
Vibrations are initiated in the cochlea by movement of the _____ against the oval window
- ANSWER stapes/stirrup
Hair cells rest within the _____, and their hairs are embedded in the ____. - ANSWER
basilar membrane; tectorial membrane
When hair cells bend, ____ channels open, causing depolarization. - ANSWER potassium
and calcium
