part of part of adjacent to adjacent to cochlear duct of membranous labyrinth tectorial membrane of cochlea acellular membrane Hensen stripe UBERON:0035806 The dark, nonstriated, V-shaped band (ridge) found on the underside of the tectorial membrane in the basal region of the cochlea, from which fine gelatinous trabeculae extend to fix the TM to the border cells, i.e. cells directly adjacent to the inner phalangeal cells. Hensen's stripe Hensen's stripe is continuous with a more external homogeneous basal layer, from which a marginal band of an amorphous substance originates; the marginal net extends from the marginal band and attaches the lateral border of the TM to Hensen's cells of the organ of Corti. Hensen's stripe and the homogeneous basal layers display interruptions through which the fibrillar structure of the TM is visible
