Reissner’s Membrane


(named after the German anatomist E. Reissner, 1824–78), the part of the wall of the membranous canal of the cochlea of the inner ear in mammals, including man, that divides the cavity of the canal from the cavity of the cochlear portion of the bony labyrinth.

The membrane consists of two very thin layers of cells. The outer layer, a fibrous connective-tissue membrane that becomes the periosteum of the bony canal, faces the side of the cavity of the bony labyrinth. The inner layer, which consists of squamous epithelial cells, faces the interior of the membranous canal of the cochlea.
