anatomical structure

Tongue is an organ composed of skeletal muscle, with mucous membrane on the surface of the bottom of the mouth, which is covered with mucus. The muscles inside are arranged in three different directions, so it can move flexibly.

Muscle organs in the mouth are covered with mucous membranes, and the protrusions on them are called the back of the tongue. Tongue can be divided into three parts: root, body and tip. There are many small nodular protrusions on the mucosa of the tongue root surface, which are called lingual tonsils. There are many protrusions with different thicknesses on the surface of the tongue, which are called lingual papillae. Some of them contain taste buds in the tongue papilla epithelium, which can feel the taste.

Under normal circumstances, the epithelium is slightly keratinized and exfoliated. Keratinized epithelium, exfoliated epithelium filled in the nipple space, saliva, food crumbs, white blood cells, etc. Form a normal thin and white tongue coating.
