SCALA VESTIBULI Meaning and
Definition
-
The Scala Vestibuli is a term derived from Latin, which translates to "vestibular staircase" in English. It refers to one of the two fluid-filled chambers within the cochlea of the inner ear. The cochlea is a spiral-shaped, snail-like structure responsible for converting sound vibrations into electrical signals that can be interpreted by the brain.
The scala vestibuli is located above the cochlear duct and is separated from it by a thin, flexible, and specialized structure called the vestibular membrane. This chamber is filled with a fluid called perilymph which plays a crucial role in transmitting vibrations stimulated by sound through the cochlea.
Sound waves enter the ear and travel through the ear canal, eventually reaching the eardrum and causing it to vibrate. These vibrations are then transmitted to the ossicles in the middle ear, which amplify the sound and send it to the oval window, a flexible membrane that connects the middle ear to the scala vestibuli.
As the sound vibrations pass through the scala vestibuli, they cause the fluid inside to move, creating pressure waves. These waves eventually reach the cochlear duct where they stimulate the hair cells responsible for converting the mechanical energy into electrical signals that can be interpreted by the auditory nerve.
In summary, the scala vestibuli is a chamber within the cochlea of the inner ear that plays a fundamental role in transmitting sound vibrations from the oval window to the cochlear duct, where the process of auditory perception begins.
