perilymph

Perilymph is found surrounding the sides and the bases of the hair cells.

Perilymph is low in potassium and high in sodium.

They contain a clear fluid, the perilymph, in which the membranous labyrinth is situated.

The electrochemical gradient makes the positive ions flow through channels to the Perilymph.

The Perilymph in Scala tympani has a very low concentration of positive ions.

The wave in the perilymph moves away from the footplate and towards the helicotrema.

For the organ of Corti the basilar membrane is permeable to perilymph.

The ionic composition of perilymph is comparable to that of plasma and cerebrospinal fluid.

Perilymph fistula - a leakage of inner ear fluid from the inner ear.

The fluids in these two tubes, the endolymph and the perilymph are very different chemically, biochemically, and electrically.

The cochlea is filled with a watery liquid, the perilymph, which moves in response to the vibrations coming from the middle ear via the oval window.

Perilymph and endolymph have unique ionic compositions suited to their functions in regulating electrochemical impulses of hair cells.

It primarily functions as a diffusion barrier, allowing nutrients to travel from the perilymph to the endolymph of the membranous labyrinth.

As the stapes pushes the oval window, pressure wave in the perilymph inside cochlea causes the BM to vibrate.

Between the outer wall of the membranous labyrinth and the wall of the bony labyrinth is the location of perilymph.

Perilymph is continuous with cerebrospinal fluid (CSF) in the subarachnoid space.

Both the scala vestibule and the scala tympani contain an extracellular fluid called perilymph.

The membranous labyrinth does not completely fill the bony labyrinth, but is partially suspended in it in a fluid (the perilymph).

It has also been suggested that perilymph and endolymph participate in a unidirectional flow that is interrupted in Ménière's disease.

Perilymph fistula, usually due to a rupture of the round or oval windows and the leakage of perilymph.

The fluid found in these two cochlear chambers is perilymph, while scala media, or the cochlear duct, is filled with endolymph.

The electric potential of endolymph is 80-90 mV more positive than perilymph due to a higher concentration of K compared to Na.

The RM separates endolymph in the cochlear duct from underlying corticolymph and perilymph of the scala tympani.

Here the border between endolymph and perilymph occurs at the reticular lamina, the endolymph side of the organ of Corti.

Fluid waves occur in the endolymph in the various parts of the membranous labyrinth in response to fluid waves in the perilymph.
