Reissner's membrane (vestibular membrane, vestibular wall) is a membrane inside the cochlea of the inner ear. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. the Peripheral organs of the Special senses the organs of Taste ( Peripheral gustatory or Elsevier, the world's largest Publisher of Medical and Scientific literature, forms part of the Reed Elsevier group In a Loudspeaker, a diaphragm (also known as the cone) is the thin semi-rigid membrane attached to the central Magnet. The cochlea is the auditory portion of the Inner ear. Its core component is the Organ of Corti, the sensory organ of hearing, which is distributed along The inner Ear is the bony labyrinth, a system of passages comprising two main functional parts the organ of hearing or Cochlea It separates scala media from scala vestibuli. The cochlear duct (or scala media) is an Endolymph filled cavity inside the Cochlea, located in between the Scala tympani and the Scala Scala vestibuli is a Perilymph filled cavity inside the Cochlea of the Inner ear. Together with the basilar membrane it creates a compartment in the cochlea filled with endolymph, which is important for the function of the organ of Corti. The basilar membrane within the Cochlea of the Inner ear is a stiff structural element that separates two liquid-filled tubes that run along the coil of the cochlea Endolymph is the fluid contained in the Membranous labyrinth of the Inner ear. The organ of Corti (or spiral organ) is the organ in the Inner ear of Mammals that contains auditory sensory cells or " Hair cells " It primarily functions as a diffusion barrier, allowing nutrients to travel from the perilymph to the endolymph of the membranous labyrinth. Diffusion is the net movement of particles (typically molecules from an area of high concentration to an area of low concentration by uncoordinated random movement Perilymph is an extracellular fluid located within the Cochlea (part of the Ear) in 2 of its 3 compartments the Scala tympani and Scala vestibuli Endolymph is the fluid contained in the Membranous labyrinth of the Inner ear. 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
Histologically, the membrane is composed of two layers of flattened epithelium, separated by a basal lamina. Histology (from the Greek = 'tissue' is the study of the microscopic anatomy of cells and tissues of Plants and In biology and medicine epithelium is a tissue composed of cells that line the cavities and surfaces of structures throughout the body The basal lamina is a layer of extracellular matrix on which Epithelium sits and which is secreted by the epithelial cells Its structure suggests that its function is transport of fluid and electrolytes. An electrolyte is any substance containing free Ions that behaves as an electrically conductive medium
Reissner's membrane is named after German anatomist Ernst Reissner (1824-1878). Anatomy (from the Greek anatomia, from ana separate apart from and temnein, to cut up cut open is a branch of Biology that is the consideration Ernst Reissner ( September 24, 1824 &ndash September 16, 1878) was a Baltic German Anatomist from Riga,
