• The olfactory cells are the chemoreceptors,

        which means that the olfactory cells have protein


        receptors that can detect subtle differences in


        chemicals.



     • These chemicals bind to the cilia, which


        conducts a nerve impulse that is carried to the

        brain.



     • The brain then translates these impulses into a


        meaningful smell.



     • During a cold, the body produces mucus which


        blocks the sense of smell, this is the reason why

        the food which we eat tastes bland.
