Anatomical terminology

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. Together with the basilar membrane, it creates a compartment in the cochlea filled with endolymph, which is important for the function of the spiral organ of Corti. It allows nutrients to travel from the perilymph to the endolymph of the membranous labyrinth. It is named after the German anatomist Ernst Reissner.

Structure

The vestibular membrane separates the cochlear duct (scala media) from the vestibular duct (scala vestibuli).[1][2]

Microanatomy

Histologically, the membrane is composed of two layers of flattened epithelium, separated by a basal lamina. Its structure suggests that its function is transport of fluid and electrolytes.[citation needed]

Function

Together with the basilar membrane, the vestibular membrane creates a compartment in the cochlea filled with endolymph. This is important for the function of the spiral organ of Corti. It primarily functions as a diffusion barrier, allowing nutrients to travel from the perilymph to the endolymph of the membranous labyrinth.

History

The vestibular membrane is also known as Reissner's membrane. This alternative name is named after German anatomist Ernst Reissner (1824-1878).
