What chamber of the cochlea is situated above the scala media?

The chamber of the cochlea that is situated above the scala media is the scala vestibuli. In the anatomy of the cochlea, there are three fluid-filled chambers: the scala vestibuli, scala media (also known as the cochlear duct), and scala tympani. The scala vestibuli is located superior to the scala media and is filled with perilymph fluid. This chamber plays a crucial role in the auditory system as it transmits sound vibrations from the oval window to the scala media and ultimately contributes to the process of hearing.

Understanding the spatial arrangement of these chambers is essential for comprehending how sound waves are transduced into neural signals. The scala media itself contains the organ of Corti, which houses the sensory hair cells responsible for detecting sound vibrations. Therefore, the naming and positioning of the scala vestibuli above the scala media are integral to the overall structure and function of the cochlea in the auditory system.
