2CHEMICAL SENSES PAPERChemical Senses PaperHumans have different senses that allow for exploration of the world around us. Two senses that often get taken for granted are taste and smell. Our chemical sense of taste holds about ten thousand taste buds while our chemical sense of smell can detect about twenty thousand different odors in ten different intensities. This is amazing because our sense of taste only has about five different variations. Normally, we can consider smell and taste vital for stopping and smelling the roses, so to speak, the uses are far more important than that. While taste and smell can help us enjoy our environment, they can also protect us, help us make connections, and recall memories.

In addition to enabling recognition of chemical moieties that provide social or nutritional clues, taste and smell receptors are expressed in many extraoral tissues, including the gastrointestinal, respiratory, and reproductive systems” (p. 1205). The process of being able to smell and taste starts with the molecules being released by substances in our environment that stimulate specific nerve cells in either the nose, throat, or mouth. From here, the cells convey messages to the brain where these certain taste or smells can be recognized. The Olfactory (smell) cells are aroused by the aromas surrounding us. For
