perilymph
Quick Summary
Perilymph is a fluid found in the inner ear, specifically between the bony labyrinth and the membranous labyrinth. It is similar in composition to other extracellular fluids like cerebrospinal fluid, with a high concentration of sodium ions and a low concentration of potassium ions.12
The perilymph is thought to be formed locally from blood plasma. It plays a role in transmitting sound vibrations from the middle ear to the cochlea, where they are then converted into nerve impulses. The perilymph is separated from the endolymph, another inner ear fluid, by the Reissner membrane.23
