11. Vibrations are transmitted into the inner ear into a fluid called endolymph , which fills the membranous labyrinth. 12. The semicircular canals are filled with endolymph , and also contain an inner membranous sleeve that form semicircular ducts. 13. Calcium carbonate is diffused through the endolymph cell membrane and the aragonite layers are permanently deposited in discrete increments. 14. The fluids in these two tubes, the endolymph and the perilymph are very different chemically, biochemically, and electrically. 15. Here the border between endolymph and perilymph occurs at the reticular lamina, the endolymph side of the organ of Corti. 16. Here the border between endolymph and perilymph occurs at the reticular lamina, the endolymph side of the organ of Corti. 17. If the endolymph fluid mixes with the fluid on the basal domain the neurons become depolarized, causing complete hearing loss. 18. The lateral wall of the cochlear duct is formed by the spiral ligament and the stria vascularis, which produces the endolymph . 19. In rare cases, the crystals themselves can adhere to a semicircular canal cupula, rendering it heavier than the surrounding endolymph . 20. Potassium is the major cation in the endolymph and is thought to be responsible for carrying the receptor currents in the cochlea.
