What is the part of tongue taste sweet?
There are 3 sides the side is sour the back is sweet and the
front is salty or spicy ....
2nd Answer:
The newer studies of the tongue with regard to taste have shown
that the entire front, top, sides, and back are pretty much equal
in what they taste; however, it has been shown that certain parts
of the tongue are first to be able to taste certain flavors. But
once there is enough concentration of a substance to be able to
taste it, all parts of the tongue taste the substance pretty
equally.
