Reissner's membrane is a membrane inside the cochlea of the inner ear. It separates scala media from scala vestibuli. Together with the basilar membrane it creates a compartment in the cochlea filled with perilymph, which is important for the function of the organ of Corti.
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.
Reissner's membrane is also known in literature as the vestibular membrane.
