Taste sensations begin when solid or liquid food is
taken into the mouth. Every taste receptor cell is capable
of recognizing all of the basic tastes: sweet, sour, salty,
and bitter. Wben food comes in contact w^ith receptor
cells, taste sensation is ti-ansmitted to the brain and the
perception of that taste sensation is directly related to tbe
concentration of the stimuli and the number of receptor
cells an individual possesses (Bartoshuk, 1989; Breslin &
