Chemical Senses Paper 2Introduction“Taste and smell are more complicated than you might think. Working together, and alone, these senses can have big impacts on everything from dementia and depression, to obesity and metabolism.” (Koerth-Baker, 2008, para.). Being able to enjoy the ability of taste allows for a person to survive just as the sense of smell allows for one to associate emotional memories to the scents. The paper will discuss the fundamentals of smell and taste, necessary changes to make a meal better, as well as the affects of losing either the sense of smell and/or the sense of smell. The two senses are highly dependent upon one another and without either of them we would miss a large part of life. Smell and TasteSmell and taste are both a part of the chemo sensation system. Being able to smell and taste begins with a process in which molecules being released by elements within the environment stimulate specific nerve cells in the throat, nose, or mouth. From this point the cells transport messages to the brain where certain smells or tastes are identified. The cells responsiblefor smell are known as olfactory cells and these cells are stimulated by the scents around us, for example flowers, baked salmon in the oven, or not so fresh gym clothes. The cells responsible for taste are known as the gustatory cells and they are scattered amongst the taste buds that couththe throat and mouth. The gustatory cells respond the elements found in our food and drinks oncethey become mixed with saliva. The cells then transport the information that has been collected through taste and send it to the nerve fibers, who then communicate the message to the brain.
