endolymph

 [en´do-limf]
the fluid contained in the membranous labyrinth of the ear; it is entirely separate from the perilymph.

en·do·lymph

(en'dō-limf), [TA]
The fluid contained within the membranous labyrinth of the inner ear; endolymph resembles intracellular fluid in composition (potassium is the main positively-charged ion).

Etymology: Gk, endon + lympha, water
the pale fluid in the membranous labyrinth (cochlear duct) of the internal ear. Compare perilymph.

canals of Scarpa - separate canals for the nasopalatine nerves and vessels.

Scarpa fascia - the deeper membranous or lamellar part of the subcutaneous tissue of the lower abdominal wall. Synonym(s): membranous layer of superficial fascia
Scarpa fluid - the fluid contained within the membranous labyrinth of the inner ear. Synonym(s): endolymph
Scarpa foramina - two openings in the line of the intermaxillary suture that transmit the nasopalatine nerve.
Scarpa ganglion - a collection of bipolar nerve cell bodies forming a swelling on the vestibular part of the eighth nerve in the internal acoustic meatus. Synonym(s): vestibular ganglion
Scarpa habenula - Synonym(s): Haller habenula
Scarpa hiatus - a semilunar opening at the apex of the cochlea through which the scala vestibuli and the scala tympani of the cochlea communicate with one another. Synonym(s): helicotrema

The stria vascularis secretes K+ into the cochlear endolymph and produces the endocochlear potential (9).
19) Moreover, since endolymph is always moving, it is too turbulent to carry specific waves.
Many experts on Meniere's disease think that a rupture of the membranous labyrinth allows the endolymph to mix with perilymph, another inner ear fluid that occupies the space between the membranous labyrinth and the bony inner ear.
These results indicate that water temperature, doubtless in association with other factors, provides a stimulus that influences the endolymph fluid chemistry of these fish, culminating in the formation of annual growth increments.
Mechanical destruction of outer hair cells also results in endolymph inflow into the organ of Corti, causing intracellular osmotic change and necrosis [11].
Additionally, the cochlea is a closed space and minor changes in the endolymph and perilymph can affect its function.
Volume and/or pressure changes in the endolymph and perilymph system (Butler, 1972 and Mayerson, 1927).
This condition is believed to be caused by an elevated level of endolymphatic pressure, which is likely due to poor absorption from the endolymphatic sac or excess secretion of endolymph, and results in distention of Reissner's membrane.
The unique ionic composition of endolymph is thought to be maintained by the stria marginal cells and vestibular dark cells in mammals (Marcus and Marcus, 1987; Marcus and Shen, 1994; Wangemann, 1995) and ionocytes in fish (Mayer-Gostan et al, 1997).
These are plausible artifacts, given that opaque zone formation is under control of a poorly understood combination of environmental and endogenous factors that influence endolymph fluid chemistry (Beckman and Wilson, 1995; Romanek and Gauldie, 1996).
Similarly, peak endolymph levels were reached in 1 to 2 hours and they, too, rapidly declined.
