The organ of Corti, or spiral organ, is the receptor organ for hearing and is located in the mammalian cochlea. ... Image showing the outer ear, middle ear, ...
The stria vascularis is a rich bed of capillaries and secretory cells; Reissner's membrane is a thin membrane that separates endolymph from perilymph; and the basilar membrane is a mechanically somewhat stiff membrane, supporting the receptor organ for hearing, the organ of Corti, and determines the mechanical wave propagation properties of the ...
English: Organ of Corti. In comparison to earlier version, I corrected 2 small errors (1: perilymph (dark purple) is found within the corti organ; 2: the tips of the inner hair cell’s stereocilia don’t touch the tectorial membrane); Added No. 14a and 14b

The cochlear duct contains the organ of Corti. [ 2 ] [ 5 ] This is attached to the basilar membrane. [ 5 ] It also contains endolymph , which contains high concentrations of K + for the function of inner hair cells and outer hair cells in the organ of Corti.
Section through the organ of Corti, showing inner and outer hair cells. The deflection of the hair-cell stereocilia opens mechanically gated ion channels that allow any small, positively charged ions (primarily potassium and calcium) to enter the cell. [10] Unlike many other electrically active cells, the hair cell itself does not fire an ...
The stria vascularis produces endolymph for the scala media, one of the three fluid-filled compartments of the cochlea. [4] This maintains the ion balance of the endolymph that surround inner hair cells and outer hair cells of the organ of Corti. [4]
