Endolymph, otherwise called Scarpa's liquid, is a reasonable liquid that can be tracked down in the membranous maze of the inward ear. It has an exceptional sythesis contrasted with other extracellular liquids in the body because of its high convergence of potassium particles and low centralization of sodium particles. Many tissues assume a vital part in the creation and support of the ionic structure of the endolymph, including Reissner's film, the striae vasculature, and the dim cells of the vestibular organs. The endolymph is isolated from the encompassing perilymph by Reissner's film, which shapes an obstruction between the two liquids. Reissner's layer gives particular particle transport and eventually the creation of endolymph from perilymph. One more significant tissue engaged with the creation of endolymph is the vascular strip that lines the horizontal mass of the cochlear pipe.

The cells found in this tissue assist with keeping a high layer potential and the centralization of potassium particles in the endolymph. Dim cells present in the cristae of the ampullary crescent trenches utilize a sodium-potassium ATP-ase siphon to effectively siphon potassium into the endolymphatic liquid. The centralization of particles made and kept up with by these different tissues makes the endolymph have a high certain likely comparative with the perilymph. The potential slope made between the two liquids gives high aversion to sound waves, bringing about depolarization and transmission of nerves to the mind for understanding. Many tissues assume a part in the guideline and reabsorption of endolymph; in any case, these cycles are not completely perceived.

Perilymph, which occupies the space inside the hard maze that encompasses the membranous maze, is comparative yet not indistinguishable in piece to other extracellular liquids of the body, like cerebrospinal liquid. The convergence of sodium particles in the perilymph is high (around 150 milliequivalents for each liter) and the centralization of potassium particles is low (around 5 milliequivalents for every liter), as in other extracellular liquids. Like these liquids, perilymph gives off an impression of being framed locally from blood plasma by transport instruments that specifically permit substances to cross slender walls. Despite the fact that it is physically workable for cerebrospinal liquid to enter the cochlea through the perilymphatic conduit, trial studies have shown it improbable that cerebrospinal liquid takes part in typical perilymph creation.

The endolymphatic sac might be engaged with liquid trade in the ear (endolymph retention, endolymph volume and strain guideline, liquid and particle carrier, mechanical valve, endolymph creation), as well as resistant guideline. The endolymphatic sac is now and again precisely decimated, shunted, or de-pressurizeed trying to turn around the normal flow of Ménière's sickness. The reasoning for this "endolymphatic shunt" activity is hard to comprehend, and as a matter of fact there is more than adequate proof that this activity is a fake treatment. Similarly as with any pipes framework, bottlenecks are quite compelling while managing stops up. With respect to utriculo-saccular channel, Bast (1937) states that the utricular side is a "cut" around 1200 µm long. The lumen changes from oval to adjust, the last option having a width of 25 to 35u. This is about the width of a few otoconia (which are around 6-15 u), and it appears to be conceivable that few together could obstruct the channel. The valve, as per Bast and displayed underneath on the right, is shaped by the impression of the mass of the uterine pipe and that piece of the foremost average mass of the uterine trench. Once more, as per Bast, the valve might help with shutting the utricular end of the utricular pipe.
