Endolymph is a clear potassium-rich lymphoid fluid that fills the cavities of the membranous labyrinth in the inner ear. Separated by the Reissner membrane, the membranous labyrinth is surrounded by the sodium-rich perilymph. For hearing, the different ion concentration between perilymph and endolymph plays a major role, while the mechanical-physical properties (principle of inertia) are … Endolymph: Structure, Function & Diseases
