| The stria vascularis forms the lateral wall of the cochlear duct. Rich in capillary vessels, the stria is composed of 3 types of cells: the marginal, intermediate and basal cells. Marginal cells bordering the cochlear duct play a key role in endolymph formation. |
On the left, a schematic representation of the cochlear duct (2) limited by the organ of corti, the Reissner's membrane (1) and the stria vascularis (3). On the right, TEM montage from a human stria vascularis showing : 1- Piece of Reissner membrane. 2- Marginal cells. 3- Basal cells. 4- Blood capillaries |
