are there any smell receptors in our mouths
These cells transmit messages to the brain, where specific smells or tastes are identified. 1  Olfactory (smell nerve) cells are stimulated by the odors around usthe fragrance from a rose, the smell of bread baking. 2  Gustatory (taste nerve) cells are clustered in the taste buds of the mouth and throat.
Smell and taste belong to our chemical sensing system (chemosensation). The complicated process of smelling and tasting begins when molecules released by the substances around us stimulate special nerve cells in the nose, mouth, or throat.
