Smell receptor. Transmission electron micrograph (TEM) of a section through the olfactory epithelium that lines the nasal cavity,showing an olfactory cell (smell receptor,blue) and its cilia (hair-like projections). Olfactory receptors are bipolar neurons (nerve cells) that transmit 'smell' information to the brain. The cilia are covered with a sticky mucus (not seen) that traps dust and other inhaled particles. Co-ordinated,wave-like beating of the cilia propels the mucus to the back of the nose (pharynx),where it is swallowed. Magnification: x5000 when printed 10 centimetres wide | |
