The Reissner membrane maintains 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. The Reissner membrane … Scala vestibuli merges with scala tympani at the helicotrema located at the apex or upper end of the cochlea. The cochlea is made up of three fluid-filled chambers (scala vestibuli, scala media, and scala tympani) that spiral around a bony core, which contains the central cochlear duct, within which sits the organ of Corti that contains the sensory hair cells and runs along the entire length of the cochlea. It terminates at the round window. C, In the middle turn, the electrode array is clearly identified in the scala vestibuli. Skala media terletak di bagian tengah c. Definition. The ionic composition of perilymph is comparable to that of plasma and cerebrospinal fluid.) is a continuous series of membrane-walled sacs that fit within the bony labyrinth c.由骨性迷路構成的耳蝸管，被兩層膜分隔成三個螺旋狀空間。. Separating the cochlear duct from the scala vestibuli is the vestibular or Reisner's membrane. The vestibular duct or scala vestibuli is a perilymph-filled cavity inside the cochlea of the inner ear that conducts sound vibrations to the cochlear duct. Pressure introduced into scala vestibuli by inward stapes motion is transmitted up the cochlear duct, through the helicotrema, and down the duct via scala tympani, where it is relieved by outward movement of the round window membrane.
