The human tongue can detect five basic tastes:
Sweet
Bitter
Salty
Umami (savory or meaty taste)
Sour
Spicy and Pungent are sensations related to pain and temperature rather than taste. They are detected through receptors called nociceptors, not the taste buds. Therefore, Spicy (4) and Pungent (7) are not considered tastes of the tongue.
