Scala media is a part of the inner ear, specifically located within the cochlea. It is filled with a fluid called endolymph and plays a crucial role in the process of hearing. The scala media contains the organ of Corti, which houses hair cells that convert sound vibrations into electrical signals sent to the brain. The scala media is one of three fluid-filled chambers in the cochlea, the other two being the scala vestibuli and scala tympani. Together, these chambers help transmit sound waves through the ear. The proper functioning of the scala media is essential for normal auditory perception and overall hearing health.
