UBPROP 0000001

The coiled portion of the membranous labyrinth located inside the cochlea. It contains endolymph. [TFD][VHOG]

UBPROP 0000003

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]
