co·chle·ar duct

[TA] a spirally arranged membranous tube suspended within the cochlea, lying between and separating the scala vestibuli and scala tympani; it begins by a blind extremity, the vestibular cecum, in the cochlear recess of the vestibule, terminating in another blind extremity, the cecum cupulare or lagena, at the cupola of the cochlea; it contains endolymph and communicates with the sacculus by the ductus reuniens; the spiral organ (of Corti), the neuroepithelial receptor organ for hearing, occupies the floor of the duct, and the stria vascularis covers the outer wall. Synonym(s): ductus cochlearis [TA], scala media [TA], Löwenberg canal, Löwenberg scala, membranous cochlea
