Reticular membrane

from Wikipedia, the free encyclopedia

The reticular membrane is the surface of the inner ear on which the head parts of the outer hair cells , which are covered with stereocilia , are located. It got its name because of the mosaic / reticulated structure.

The outer hair cells sit on supporting cells, the so-called outer phalangeal cells (Deiters cells). These have narrow, apical runners that lead up along the outer hair cells and expand there to form head plates, thus forming the reticular membrane . Each head part ( apex ) of the outer hair cells is surrounded by a collar made of head plates of these phalangeal cells. Through numerous tight junctions, these form a diffusion barrier between the endolymph of the cochlear duct and the Corti lymph of the organ of Corti .
