The sense of taste - Essay Example Also referred to as gustation the sense of taste involves a complex interaction between receptors on the individualÃ¢â¬â¢s tongue and mental perception. As the saliva in oneÃ¢â¬â¢s mouth breaks down food, the taste sense receptors in the tongue relay messages to the neurological aspects of the nervous system. As one might expect there are a broad array of receptors in this region, which has led some researchers to argue that there is actually more than one sense of taste; instead they contend taste constitutes a variety of distinguishable characteristics. For instance, of the most readily distinguishable receptors function to identify tastes for sweet, salty, sour, and bitter; another receptor, referred to as the umami receptor, detects the amino acid glutamate (Ã¢â¬ËUmani Taste ReceptorÃ¢â¬â¢).

ItÃ¢â¬â¢s also true that as individuals age their taste receptors will correspondingly change. At an early age taste buds function around the entire individualÃ¢â¬â¢s mouth, but as individuals age these surrounding taste buds shrink so that they are ultimately limited to predominantly the tongue (Ã¢â¬ËTasteÃ¢â¬â¢).
