Definition of Membranous labyrinth
The membranous labyrinth is a collection of fluid filled tubes and chambers in the inner ear which contain the receptors for the senses of equilibrium and hearing. It is lodged within the bony labyrinth and has the same general form; it is, however, considerably smaller and is partly separated from the bony walls by a quantity of fluid, the perilymph.
In certain places, it is fixed to the walls of the cavity.
The membranous labyrinth contains fluid called endolymph. The walls of the membranous labyrinth are lined with distributions of the cochlear nerve, one of the two branches of the vestibulocochlear nerve. The other branch is the vestibular nerve.
