| 21. | However, both the somatic motor and the hair bundle motor produce significant displacements of the basilar membrane.
|
| 22. | A very strong movement of the basilar membrane due to very loud noise may cause hair cells to die.
|
| 23. | Thus, damage to the OHCs results in the reduction of sensitivity of the basilar membrane to weak sounds.
|
| 24. | At the base of the basilar membrane it is narrow and stiff and is most responsive to high frequencies.
|
| 25. | Boettcher cells are polyhedral cells on the basilar membrane of the cochlea, and are located beneath Claudius cells.
|
| 26. | These cells sit directly above a basilar membrane ( BM ) that has high sensitivity for differences in frequency.
|
| 27. | Further along the auditory pathway, the movement of the basilar membrane results in the stimulation of primary auditory neurons.
|
| 28. | Place theory holds that the perception of pitch is determined by the place of maximum excitation on the basilar membrane.
|
| 29. | The basilar membrane on the tympanic duct presses against the hair cells of the organ as perilymphatic pressure waves pass.
|
| 30. | They do this by receiving mechanical signals or vibrations along the basilar membrane, and transducing them into electrochemical signals.
