Organ of Corti - Stria Vascularis (mouse)

The stria vascularis:

produces endolymph for the scala media.
is highly vascularised
consists of three layers of distinct cell types


Marginal cells Intermediate cells Basal cells
line the lumen of the cochlear duct melanocyte-like cells lie between the marginal and basal cell layers mesenchymal spiral ligament fibrocytes
derived from epithelia derived from the neural crest derived from otic mesenchyme PMID 21925491

Within the cochlea, the specialised structure required for converting mechanical vibration into an electrical signal occurs at the organ of Corti. Named after Alfonso Giacomo Gaspare Corti (1822–1876), an Italian anatomist who discovered this structure in 1851.

This histology image is a section through one turn of the cochlea showing the organ of corti.
