The gustatory system is the system that determines the senses of taste. Taste is detected by molecules that enter the mouth, whether in liquid or solid form (Goldstein, 2010). Taste can be known as a gatekeeper, whose purpose is to create a connection between the effect of the substance and the quality of the taste. Most people like sweet and savory compounds that contain nutritional value and are essential for comfort. Not only do sweet compounds produce a satisfying sensation, but they also cause an anticipatory metabolic response that prepares the gastrointestinal system for the digestion of these foods and causes an automatic acceptance response (Goldstein, 2010). Acidic and bitter compounds are seen as unpleasant and unpleasant. Acidic and bitter compounds work in the opposite way to sweet foods, triggering automatic rejection responses, which help protect the body from bacteria and other harmful substances (Goldstein, 2010). People craving salty compounds indicate that their sodium levels are low and need to be replenished. There are five basic taste sensations we experience: sweet, sour, salty, bitter and umami. The umami taste can be described as savory or meaty and is also associated with monosodium glutamate or MSG (Travis, 1999). MSG is a flavoring that can be found in most Asian cuisines and fast foods. Sweet compounds bind to G protein-coupled receptors (GPCRs) on the surface of the cell (The sense of, 2013). The sensation of sour taste occurs as a result of electrolysis and produced by galvanic current (Ziehen, 1895). As for the salty sensation, the basic table salt receptor allows sodium ions to enter the cell tightly and trigger action potentials in sensory neurons. Bitter receptors can also......middle of paper......des and some medications are factors in taste loss. Taste disorders can be treated. If the original cause of taste loss is due to illness or injury, after and if the condition is healed, taste sensations will be recovered. If a loss of taste has occurred due to specific medications, the prescription can simply be changed or changed; and you will regain the ability to taste. The tongue is an amazing organ and has a significant function for the body. There are different taste buds, taste cells, taste receptors, nerves, and signals that are sent to the brain for people to enjoy delicious foods. Although many think that taste is created from the top of the tongue, it actually starts from the sides and tip of the tongue. Some may experience loss of taste due to disorders, but treatments exist to regain the five sensations again.
