K14.1: Geographic tongue
The tongue is mostly made up of muscles. The tongue is important for chewing, swallowing and speaking. It is connected to the back of the throat. There are many taste buds on the surface of the tongue. The taste buds have lots of small nerves, allowing us to perceive taste.
On your tongue you can see red and white patches, like a map. Patches like these affect the tissue on the surface of the tongue. This is why the tongue looks different. You may also feel a burning or mild soreness on your tongue.
