What tastes does the tongue detect?
There are different taste buds in our tongue. There is sweet at the front, salty at the middle, and bitter and sour all way further to the end of your tongue.

How does tongue detect spiciness?
There is not an actual 'spicy' taste bud. When you get oils from a chilli pepper on you hands it starts to burn quickly, this is similar to what happens to your tongue. Capsaicin, the chemical that produces the sensation of spiciness is damaging some of the nerves at the surface of the tongue. Hence, someone who eats spicy food regularly will grow a tolerance for even spicier foods as the nerves on the tongue have become 'numb' to capsaicin.
Why does a spray of water come out of mouth when yawning?
The sublingual caruncle is found under your tongue (either side of the frenulum - the small folds going from your tongue and the cavity floor).
