UPPER JAW Meaning and Definition

1. The upper jaw, also referred to as the maxilla, is an anatomical structure in vertebrates, including humans, that forms the front portion of the skull. It is positioned above the lower jaw or mandible, and together they enclose the oral cavity and house the teeth.

   In humans, the upper jaw consists of two opposing maxillary bones, which are fused together during development. These bones form the upper dental arch, where the majority of the teeth are anchored. The upper jaw provides support for the nose, as it contributes to the formation of the nasal cavity and its surrounding structures. It also plays a vital role in the formation of the eye sockets, known as the orbits.

   The maxilla extends upwards and connects with other structures of the skull, such as the frontal bone, nasal bones, and ethmoid bone. It contains several openings, including the maxillary sinuses, which are air-filled cavities. These sinuses help reduce the weight of the skull and have a role in resonation during speech.

   The upper jaw is responsible for essential functions, including biting, chewing, and speaking, as it houses the upper set of teeth and helps in the articulation of various sounds. Furthermore, the upper jaw contributes to the overall facial appearance and symmetry, playing a crucial role in aesthetics.

2. Superior maxilla, maxilla.
