| Anatomical terminology | |
The stria vascularis of the cochlear duct is a capillary loop in the upper portion of the spiral ligament (the outer wall of the cochlear duct or scala media). It produces endolymph for the scala media in the cochlea.
Structure
The stria vascularis is part of the lateral wall of the cochlear duct.[1] It is a somewhat stratified epithelium containing primarily three cell types:
- marginal cells,scala media.
- intermediate cells,[1] which are pigment-containing cells scattered among capillaries.
- basal cells,[1] which separate the stria vascularis from the underlying spiral ligament.[2] They are connected to basal cells with gap junctions.[1]
The stria vascularis also contains
]Function
The stria vascularis produces
outer hair cells of the organ of Corti.[4] It secretes lots of K+,[1][4] and may also secrete H+.[1]
