Membranous labyrinth The membranous labyrinth. Latin labyrinthus membranaceus Gray's subject #232 1051 Artery labyrinthine artery
The receptors for the senses of equilibrium and hearing are housed within a collection of fluid filled tubes and chambers known as the membranous labyrinth. The membranous labyrinth 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, the endolymph, and on its walls the ramifications of the acoustic nerve are distributed.
The membranous labyrinth is also the location for the receptor cells found in the inner ear.
