| 1. | The hair bundle consists of an array of actin-based stereocilia.
|
| 2. | Microfilament formation by treadmilling has been found to be atypical in stereocilia.
|
| 3. | The stereocilia found on OHCs are in contact with the tectorial membrane.
|
| 4. | The identity of the mechanosensitive channels in the stereocilia is still unknown.
|
| 5. | When a wave of sound deflects the stereocilia, the channel opens.
|
| 6. | This deflects the cupula and bends the stereocilia within.
|
| 7. | Secondly, the stereocilia might become distorted or destroyed.
|
| 8. | There are approximately 140 stereocilia on each OHC.
|
| 9. | Therefore, when the basilar membrane moves due to vibrations, the stereocilia bend.
|
| 10. | The stereocilia in a hair bundle are arranged in multiple rows of different heights.
