Endolymph - Wikipedia
Endolymph is the fluid contained in the membranous labyrinth of the inner ear. The major cation in endolymph is potassium, with the values of sodium and potassium concentration in the endolymph being 0.91 mM and 154 mM, respectively. [1] It is also called Scarpa's fluid, after Antonio Scarpa. [2]

2023年3月31日 · The endolymphatic sac (ES) is a membranous structure in the inner ear located partly in the temporal bone and partly within the dura of the posterior fossa. It contains endolymph, which is similar in chemical makeup to intracellular fluid (high in K, low in Na). It was first described by Cotugno, in 1760 (Corrales and Mudry, 2017).
