The perilymph is
WebbPerilymph definition, the fluid between the bony and membranous labyrinths of the ear. See more. WebbPerilymph has an ionic composition similar to extracellular fluid found elsewhere in the body (i.e., it is K+ -poor and Na + -rich), and it fills the scalae tympani and vestibule. Hearing depends on the high K + concentration in endolymph that bathes the apical membranes of sensory hair cells.

WebbEndolymph has a high positive potential (80–120 mV in the cochlea), relative to other nearby fluids such as perilymph, due to its high concentration of positively charged ions. It is mainly this electrical potential difference that allows potassium ions to flow into the hair cells during mechanical stimulation of the hair bundle. Perilymph is an extracellular fluid located within the inner ear. It is found within the scala tympani and scala vestibuli of the cochlea. The ionic composition of perilymph is comparable to that of plasma and cerebrospinal fluid. The major cation in perilymph is sodium, with the values of sodium and potassium … Visa mer The inner ear has two major parts, the cochlea and the vestibular organ.
