The sense of taste (also gustatory from Latin gustare = to taste, to savour) serves to control the ingested food. Like smell, it is one of the chemical senses. In a broader sense, the sensation of taste is a complex interaction of the gustatory (tasting) sense of taste and the olfactory (smelling) sense of smell. This is further complemented with tactile or trigeminal tactile, pain and temperature information from the oral cavity. The latter includes, for example, the sensations of sharp (hot) and astringent (effect of tannin-rich red wines, which should not be confused with bitter). In a narrower sense, however, taste consists of relatively few different tastes absorbed via the tongue and partly also via the pharyngeal mucosa.
