cochlear duct of membranous labyrinth
An endolymph filled cavity inside the cochlea, located in between the scala tympani and the scala vestibuli, separated by the basilar membrane and Reissner's membrane (the vestibular membrane) respectively. Houses the organ of Corti[WP]. [ http://en.wikipedia.org/wiki/Cochlear_duct ]
Synonyms: scala medias, cochlear duct, Reissners canal, Reissner's canal, cochlea duct

The coiled portion of the membranous labyrinth located inside the cochlea. It contains endolymph. [TFD][VHOG]
In gnathostomes, each membranous labyrinth has three semicircular ducts that connect with a chamber known as the utriculus. (...) In all gnathostomes, the utriculus connects ventrally with a larger sac, called the sacculus (...) In most groups of gnathostomes, the caudoventral evagination of the sacculus forms a small lagena, and in some diapsids and mammals the lagena develops into a longer duct. The lagena becomes greatly elongated in therians and coils to form the cochlear duct.[well established][VHOG]
