Cartoon diagram of major cell types of the olfactory mucosa in vivo The cilia of the Cl−-accumulating ORNs are exposed to mucus. The mucus is generated by Bowman's glands (BG) and sustentacular cells (Sus) (Farbman, 1992). The ORN cell bodies sit in an extracellular space containing basal cells (not shown) and sustentacular cells. The Bowman's glands, ORN axons and basal feet of the sustentacular cells sit near or in a well-vascularized lamina propria. The ORN-containing olfactory epithelium and its underlying lamina propria comprise the olfactory mucosa.
