-
the fluid-filled cochlea is divided into 3 compartments called SCALAE
-
scala vestibuli and tympani contain perilymph, which has a composition similar to extracellular fluid
-
scala media contains endolymph, which has a high K+ concentration
- the auditory receptor cells (called hair cells) are found in the organ of Corti, which is located on the basilar membrane separating scala tympani from scala media
