The taste buds are located in the papillae (puh PILL ee), which are projections, or bumps, on the upper surface of the tongue that sense flavors; such as, bitter, sweet, salty, and sour.2. The movable fleshy organ attached to the bottom of the inside of the mouth of humans and most animals, used for tasting, licking, swallowing, and, in humans, speech.
As stated previously, the tongue is a strong muscle anchored to the floor of the mouth. It is covered by the lingual membrane which has special areas to detect tastes.
The tongue is attached to the lower jaw and to the hyoid bone (a small, U-shaped bone that lies deep in the muscles at the back of the tongue) above the larynx.
Again, as defined above, on the top surface of the tongue there are small nodules called papillae that give the tongue its rough texture.
Between the papillae at the sides and base of the tongue, there are small bulb-like structures that are the taste buds. The muscle fibers of the tongue are heavily supplied with nerves.
The tongue aids in the formation of the sounds of speech and coordinates its movements to aid in swallowing.
The adjective for tongue is "lingual"; so, the papillae of the tongue are the lingual papillae.
