Sensation
Taste, or gustation, is the ability to detect sensory changes in the tongue, through the use of taste buds, situated deep into the papillae. Intriguingly, the sense called gustation is in fact comprised of varying ratios of multiple sensory systems, shifting in importance and attention as food is chewed, tasted and swallowed. These include the taste buds, the sense of touch in the structures of the mouth and digestive system, chemical sensation of irritation in the trigeminal nerve system, and unique receptors for sensing the properties of water located at the rear of the oral cavity.
