    • n jaw One of the bones which form the skeleton or framework of the mouth; a maxilla or mandible; these bones collectively. The jaws in nearly all vertebrates are two in number, the upper and the lower. The upper jaw on each side consists chiefly of the superior maxillary or supramaxilla, and of an intermaxillary bone or premaxilia, both of which commonly bear teeth in mammals, reptiles, batrachians, and some fossil birds. The lower jaw in mammals is a single bone, the inframaxillary, inframaxilla, or mandible, or one pair of bones united at the middle line by a symphysis. In vertebrates below mammals this bone is represented by several pieces, its bony elements becoming quite complex in birds and most reptiles and many fishes. The mandible, and especially its terminal element when there are several, commonly bears teeth like the upper jaw. As a rule, it is movably articulated with the rest of the skull. In mammals this articulation is direct, and is known as the temporomaxiillary. In birds it is indirect, by intervention of a quadrate bone; and in the lower vertebrates various other modifications occur. See cuts under Cyclodus, Gallinæ, Felidæ, and skull.
    • n jaw The bones and associated structures of the mouth, as the teeth and soft parts, taken together as instruments of prehension and mastication; mouth-parts in general: commonly in the plural. In most invertebrates, as insects and crustaceans, the jaws are much complicated, and consist essentially of modified limbs, maxillipeds, gnathopods, or jaw-feet; and the opposite parts work upon each other sidewise, not up and down. Often used figuratively. See cut under mouth-part.
