In vertebrates, the lower jaw, dentary or mandible is the mobile component that articulates at its posterior processes, or rami (singular ramus), with the temporal bones of the skull on either side; the word jaw used in the singular typically refers to the lower jaw. The upper jaw or maxilla is more or less fixed with the skull and is composed of two bones, the maxillae, fused intimately at the median line by a suture; incomplete closure of this suture and surrounding structures may be involved in the malformation known as cleft palate. The maxillary bones form parts of the roof of the mouth, the floor and sides of the nasal cavity, and the floor of the orbit (eye socket). The jaws typically accommodate the teeth or form the bases for the attachment of a beak.
