reticularislamina
Reticular lamina, or lamina reticularis, is a thin, lattice-like extracellular layer that forms the apical boundary of the sensory epithelium in the organ of Corti within the cochlea. It is composed primarily of the apical surfaces and junctional complexes of the hair cells (inner and outer) and of supporting cells such as pillar cells and Deiters’ cells, whose processes interdigitate to create a continuous sheet across the organ. The reticular lamina lies just beneath the tectorial membrane and above the cuticular plates of the hair cells.
Functionally, the reticular lamina acts as the roof of the organ of Corti, separating the endolymph in
Development and clinical relevance are tied to its role as a boundary within the cochlea. The reticular
