n. the sense for the appreciation of the flavour of substances in the mouth. The sense organs responsible are the *taste buds on the surface of the *tongue, which are stimulated when food dissolves in the saliva in the mouth. It is generally held that there are four basic taste sensations – sweet, bitter, sour, and salt – but two others – alkaline and metallic – are sometimes added to this list.
the sensory receptors concerned with the sense of taste (see illustration). They are located in the epithelium that covers the surface of the *tongue, lying in the grooves around the papillae, particularly the circumvallate papillae. Taste buds are also present in the soft palate, the epiglottis, and parts of the pharynx. When a taste cell is stimulated by the presence of a dissolved substance impulses are sent via nerve fibres to the brain. From the anterior two-thirds of the tongue impulses pass via the facial nerve. The taste buds in the posterior third of the tongue send impulses via the glossopharyngeal nerve.... taste buds
