The vestibular membrane, vestibular wall or Reissner's membrane is a membrane inside the cochlea of the inner ear. It separates the cochlear duct from the vestibular duct. It helps to transmit vibrations from fluid in the vestibular duct to the cochlear duct.

The Reissner membrane forms a selective barrier between the two fluids. Blood-endolymph and blood-perilymph barriers, which control the passage of substances such as drugs from the blood to the inner ear, appear to exist as well.

Reissner's membrane roofs the compartment containing the hair cells. In certain conditions in which endolymph pressure is increased (e.g., Ménière's disease), Reissner's membrane may bow out or rupture.

Here we combine theoretical and experimental studies to show that mechanical signals can be transmitted by waves on Reissner’s membrane, an elastic structure within the cochea. We develop a theory for wave propagation on Reissner’s …

Reissner’s membrane, also known as the vestibular membrane, is a thin, delicate membrane that separates the scala media from the scala vestibuli in the cochlea. It is located within the inner ear and is essential for hearing.

The vestibular (or Reissner’s) membrane is an elastic membrane that serves as a barrier, separating the scala vestibuli and the cochlear duct in the cochlea. It is notably thinner than the basilar membrane, which is the other elastic membrane associated with the cochlear duct.

the membrane separating the cochlear duct from the vestibular canal; it consists of squamous epithelial cells with microvilli toward the ductus, a basement membrane, and a thin layer of connective tissue toward the scala.

Reissner’s membrane is a very thin membrane first reported by Reissner in 1851. In the embryonic stage it is structured by the inner ectodermal layer and several outer mesodermal layers.

Reissner's membrane is approximately 2-3 J.lm thick and separates the scala vestibuli and the cochlear duct, extending from the osseous spiral lamina to the lateral wall.

Reissner's membrane a membrane situated in the cochlea of the inner ear, that separates the middle canal from the vestibular canal, named after the German physiologist E. Reissner.
