Anatomical terminology |
The cochlear duct (or scala media) is an endolymph filled cavity inside the cochlea, located in between the tympanic duct and the vestibular duct, separated by the basilar membrane and Reissner's membrane (the vestibular membrane) respectively.
The cochlear duct houses the organ of Corti.

- BACKGROUND: Murine Zic genes (Zic1-5) are expressed in the dorsal hindbrain and in periotic mesenchyme (POM) adjacent to the developing inner ear. Zic genes are involved in developmental signaling pathways in many organ systems, including the ear, although their exact roles haven't been fully elucid
