Perilymph is a clear, extracellular fluid found in the inner ear, specifically in the spaces surrounding the cochlea and vestibular structures. It is primarily composed of water, electrolytes, and proteins, with a high concentration of sodium ions and a lower concentration of potassium ions compared to endolymph, another fluid in the inner ear. This ionic composition is crucial for maintaining the electrochemical gradients necessary for hearing and balance.
Perilymph and endolymph are fluids found in the inner ear. Perilymph helps transmit sound vibrations to the cochlea, while endolymph plays a role in maintaining the balance and spatial orientation of the body by stimulating hair cells in the vestibular system.
The movement of the perilymph activates the hair cells in the cochlea, which are responsible for detecting sound vibrations and transmitting auditory signals to the brain via the auditory nerve.

That is called vertigo, which is a sensation of spinning or dizziness that occurs due to disturbances in the inner ear, particularly the cochlea or semicircular canals, where the perilymph fluid moves. This can lead to a feeling of imbalance or motion sickness.
Vibration of the tympanic membrane causes movement of the ear ossicles, resulting in the in-and-out vibration of the stapes in the oval window. That touches the perilymph in the scala vestibuli.
The fluid of the inner ear, called perilymph, is contained within the bony labyrinth of the cochlea and vestibular system while surrounding the membranous labyrinth, which contains endolymph. Perilymph helps transmit sound vibrations and maintains balance within the inner ear.
Perilymph is a fluid present in the scala vestibuli and scala tympani which are the perilymph compartments of the inner ear. It has the same ionic concentration as the extracellular fluid present in the entire body
Perilymph is an extracellular fluid located within the cochlea (part of the ear) in 2 of its 3 compartments; the scala tympani and scala vestibuli. The ionic composition of perilymph is comparable to that of plasma and cerebrospinal fluid. The major cation of perilymph is sodium.
Perilymph and endolymph are fluids found in the inner ear. Perilymph helps transmit sound vibrations to the cochlea, while endolymph plays a role in maintaining the balance and spatial orientation of the body by stimulating hair cells in the vestibular system.

Perilymph is found in the scala vestibuli and scala tympani of the cochlea in the inner ear. It helps transmit sound vibrations from the middle ear to the inner ear.
The movement of the perilymph activates the hair cells in the cochlea, which are responsible for detecting sound vibrations and transmitting auditory signals to the brain via the auditory nerve.

Perilymph sloshes around in the cochlea, a spiral-shaped, fluid-filled tube in the inner ear. This fluid plays a crucial role in transmitting sound signals to the brain for processing.
