| 11. | The fluids in these two tubes, the endolymph and the perilymph are very different chemically, biochemically, and electrically.
|
| 12. | Here the border between endolymph and perilymph occurs at the reticular lamina, the endolymph side of the organ of Corti.
|
| 13. | Vestibular duct perilymph vibrations bend organ of Corti outer cells ( 4 lines ) causing prestin to be released in cell tips.
|
| 14. | This works as a type of shunt to eliminate excess perilymph fluid from the perilymphatic space around the cochlea of the ear.
|
| 15. | There is connection from the subarachnoid space to the bony labyrinth of the inner ear making the cerebrospinal fluid continuous with the perilymph.
|
| 16. | Whereas the perilymph is rich in sodium ions, the endolymph is rich in potassium ions, which produces an ionic, electrical potential.
|
| 17. | Beta-2 transferrin would also be positive in patients with perilymph fluid leaks, as it is also present in inner ear perilymph.
|
| 18. | Beta-2 transferrin would also be positive in patients with perilymph fluid leaks, as it is also present in inner ear perilymph.
|
| 19. | The fluid found in these two cochlear chambers is perilymph, while scala media, or the cochlear duct, is filled with endolymph.
|
| 20. | The purpose of the perilymph-filled tympanic duct and vestibular duct is to depolarise and send impulses to the brain via the cochlear nerve.
