Cochlear duct

The cochlear duct of the membranous labyrinth (or simply cochlear duct also Reissner`s canal or scala media, latin: ductus cochlearis) is an endolymph-containing membranous tube within the cochlea situated between the scala vestibuli and scala tympani, bounded by the basilar membrane and the Reissner`s membrane. The cochlear duct contains the organ of Corti, which is located on its lower wall and plays an essential role in the sense of hearing.
