| 1. | For the organ of Corti the basilar membrane is permeable to perilymph.
|
| 2. | Perilymph is found surrounding the sides and the bases of the hair cells.
|
| 3. | Perilymph is low in potassium and high in sodium.
|
| 4. | Perilymph is continuous with cerebrospinal fluid ( CSF ) in the subarachnoid space.
|
| 5. | The wave in the perilymph moves away from the footplate and towards the helicotrema.
|
| 6. | Both the scala vestibuli and the scala tympani contain an extracellular fluid called perilymph.
|
| 7. | The RM separates endolymph in the cochlear duct from underlying corticolymph and perilymph of the scala tympani.
|
| 8. | Its fluid, endolymph, also contains electrolytes and proteins, but is chemically quite different from perilymph.
|
| 9. | These motors ( outer cells ) amplify the perilymph vibrations that initially incited them over 40-fold.
|
| 10. | Thus, beta-2 transferrin in otorrhea would be suggestive of either a CSF leak or a perilymph leak.
