Fluid Present in the Labyrinths
The labyrinth is a complex system of interconnecting channels and cavities present in the inner ear. It is composed of two parts, the osseous and membranous labyrinths. Between these two labyrinths is a fluid called perilymph.
Perilymph
Perilymph is a clear, watery fluid that fills the space between the osseous and membranous labyrinths of the inner ear. It is similar in composition to cerebrospinal fluid found in the brain and spinal cord. The perilymph is important for maintaining the electrochemical balance of the inner ear, which is essential for proper hearing and balance.
Function of Perilymph
The perilymph acts as a cushioning fluid that protects the delicate structures of the inner ear from damage due to excessive vibrations. It also helps to transmit sound waves from the middle ear to the cochlea, where they are converted into electrical signals that are sent to the brain for interpretation.
Conclusion
In conclusion, the fluid present between the osseous and membranous labyrinths of the inner ear is called perilymph. It plays a crucial role in maintaining the electrochemical balance of the inner ear, protecting it from damage and transmitting sound waves from the middle ear to the cochlea.

There is the bony labyrinth. It acts as a tunnel in which lie the membranous labyrinth. The bony labyrinth encloses perilymph whereas the membranous labyrinth encloses endolymph hence the fluid between them is perilymph.
