 | | In arthropods, the jaws are chitinous and oppose laterally, and may consist in mandibles, chelicerae, or, loosely, pedipalps. |
| | In vertebrates, the lower jaw 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. |
