| 41. | The mechanoreceptors are hair cells, the same mechanoreceptors for vestibular sense and hearing.
|
| 42. | The sensory cells within neuromasts are polarized hair cells contained within a gelatinous cupula.
|
| 43. | They provide mechanical coupling between the basement membrane and the mechanoreceptors on the hair cells.
|
| 44. | The structures that enable the saccule to gather this vestibular information are the hair cells.
|
| 45. | Nerve fiber innervation is much denser for inner hair cells than for outer hair cells.
|
| 46. | Nerve fiber innervation is much denser for inner hair cells than for outer hair cells.
|
| 47. | Efferent synapses occur on outer hair cells and on afferent axons under inner hair cells.
|
| 48. | Efferent synapses occur on outer hair cells and on afferent axons under inner hair cells.
|
| 49. | This pushes the hair cell processes down and prevents them from moving side to side.
|
| 50. | No current therapies or reparative measures exist to replace such defective hair cells in humans.
