Taste. The end organs of taste are chiefly located in the tongue (q.v.). The nerves concerned are the glosso-pharyngeal and certain branches of the fifth nerve. Most of the sensations of taste are to a large extent dependent upon the sense of smell; there are, however, four primary taste sensations apart from olfactory sensations, which are classed as the sensations of sweets, bitters, acids, and salines.
