The nose contains mucus-coated receptors which are specialised for receiving the sense of smell and are called olfactory receptors. These are made up of olfactory epithelium which consists of three kinds of cells. The neurons of the olfactory epithelium extend from theoutside environment directly into a pair of broad bean-sized organs called olfactory bulb. Olfactory bulbs are extensions of the brains limbic system.
