The tongue is an important accessory organ in the digestive system. The tongue is used for crushing food against the hard palate, during mastication and manipulation of food for softening prior to swallowing.

For example, scalloping of the tongue is said to indicate qi vacuity. [13] Some modern medical sources still describe the tongue as "the mirror of physical health". [14] This is related to the high rate of turnover of the oral mucosa compared to the skin, which means that systemic conditions may manifest sooner in the mouth than the skin.
The thin strip of tissue that runs vertically from the floor of the mouth to the undersurface of the tongue is called the lingual frenulum. It tends to limit the movement of the tongue, and in some people, it is so short that it actually interferes with speaking. A hump of tissue near the base of the tongue houses a series of saliva gland ducts.

Abnormal swallowing patterns push the upper teeth forward and away from the upper alveolar processes and cause open bites.
The floor is formed by the mylohyoid muscles and is occupied mainly by the anterior two-thirds of the tongue. A mucous membrane – the oral mucosa, lines the sides and under surface of the tongue to the gums, and lines the inner aspect of the jaw . It receives secretions from the submandibular and sublingual salivary glands.
Tongue rolling is the ability to roll the lateral edges of the tongue upwards into a tube. The tongue's intrinsic muscles allow some people to form their tongues into specific shapes. Rolling the tongue into a tube shape is often described as a dominant trait with simple Mendelian inheritance , and it is commonly referenced in introductory and ...
