1. A mobile mass of muscular tissue covered with mucous membrane and located in the oral cavity; SYN. lingua, glossa, clapper.
In tetrapod vertebrates, a muscular organ usually attached to the floor of the mouth. It has a thick root attached to a U-shaped bone (hyoid), and is covered with a mucous membrane containing nerves and taste buds. It is the main organ of taste. The tongue directs food to the teeth and into the throat for chewing and swallowing. In humans, it is crucial for speech; in other animals, for lapping up water and for grooming, among other functions. In some animals, such as frogs, it can be flipped forward to catch insects; in others, such as anteaters, it serves to reach for food found in deep holes.
The hyoid apparatus, to which the tongue is attached, is formed from what were gill supports in fishes.
2. The tongue of certain animals used as meat.
3. The flap of material under the laces of a shoe or boot.
4. Any long thin projection that is transient; SYN. knife.

Organ u usnoj duplji, mišićni organ koji se sastoji od većeg broja mišića pokrivenih sluznicom. Leži na zadnjem delu poda usne duplje, za koji je pričvršćen. Pri zatvorenim ustima potpuno ispunjava usnu duplju, tako da dodiruje nepce i zube.
Svojim mišićnim delom jezik vrši pokrete, te na taj način učestvuje u žvakanju, gutanju, stvaranju glasova i sisanju. Sluznica jezika predstava sedište čula ulkusa, a preko završetaka posebnih živaca omogućuje prijem utisaka osećaja, bola i temperature.
