cochlea *scala vestibuli* and the round window is directly connected to the scala tympani (where sound dissipates)"The scala vestibuli is continuous with the vestibule near the base of the cochlea, where it abuts the oval window."From: Human Anatomy, 5th Edition Marieb, Mallatt, and Wilhelm
it is responsible for conducting sound vibrations. Both the scala tympani and scala vestibuli are filled with the fluid known as perilymph.
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.

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.
The walls of the hollow cochlea are made of bone, with a thin, delicate lining of epithelial tissue.

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
