Cochlear duct of membranous labyrinthUBERON concept
Preferred Label : cochlear duct of membranous labyrinth;
Uberon definition : 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].;

Uberon Homology note : 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];
