There are four distinct tastes that the human tongue can detect. Each is identified by different taste buds, as shown in this illustration.

taste bud

(tāst)
Any of numerous sense organs on the tongues of most vertebrate animals that are sensitive to four types of taste: sweet, sour, salty, or bitter.

Each taste bud can detect five flavors: sweet, sour, bitter, fruity, and umami (meaty).
Many taste bud diagrams present distinct "taste-zones.
Summary: TEHRAN (FNA)- A team of investigators discovered how ATP - the body's main fuel source - is released as the neurotransmitter from sweet, bitter, and umami, or savory, taste bud cells.
