WebJun 30, 2024 · The loss of perilymph alters the balance between perilymph and endolymph within the membranous labyrinth. PLF is thus a form of inner ear fluid imbalance. … WebSep 16, 2024 · Endolymph in cochlear is characterized by extremely high resting potential called EP, in addition to high K + concentration. In contrast, in the vestibular endolymph, the K + concentration is high, but no EP can be detected. Claudin-14 may be necessary for maintaining a barrier to resist EP, but not K +. 3.2.3.
