Taste buds
A unique organ, the tongue is a very mobile bundle of muscles covered with an extremely sensitive surface. The muscles in the tongue can flatten it, curl up the tip and even the edges when you whistle.
The tongue is made up of muscle, nerves and blood vessels. The top surface of the tongue is covered in taste buds.
Yes, there are nerves in the middle of your tongue. There are several different kinds of nerves. Some are pain nerves. Other nerves measure pressure, temperature, and location. Different areas of the body have different mixtures of these nerves. For example, the hands have more nerves that sense temperature than most of your skin, and the fingertips are more sensitive to pressure than most areas. The tongue is not extremely sensitive to pressure on the outside, but is very sensitive to it on the inside. This is why a light bite of the tongue doesn't hurt, but suddenly hurts more when the bite is harder.
Finger tip has numerous nerve endings and that's why they are too sensitive. Similar is the case with tongue which has numerous nerves in order to propagate the taste sensation from the taste buds on the tongue

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.
The finger is more sensitive to touch. The tongue is more sensitive to temperature. Test it out for your self!
Taste occurs over the whole surface of the tongue. Certain areas of the tongue may be more sensitive to one of the five tastes humans can register: sweet, bitter, salt, sour, and savory (like garlic).
The bitter ones are the most sensitive.
