The notion that specific tastes are confined to certain areas of the tongue is a myth debunked by recent research. The taste map showing sweet at the tip, salty on the sides, sour behind, and bitter in the back is inaccurate.
Taste receptors are not limited to the tongue but are also found in various organs like the gastrointestinal tract, liver, pancreas, brain, and lungs. These receptors help in detecting molecules for metabolism.
