Olfactory Membrane. The olfactory membrane, or epithelium, is a layer of cells on the roof of the nasal cavity. It is made up of three layers of cells: the supporting cells, the olfactory receptor cells, and the basal cells.Supporting cells are similar to glial cells and help produce mucus.Basal cells are the source of new receptors. Olfactory receptor cells, actually neurons, are the site of transduction.t is made up of three layers of cells: the supporting cells, the olfactory receptor cells, and the basal cells.
