maxilla

 [mak-sil´ah] (L.)
one of two identical bones that form the upper jaw. The maxillae meet in the midline of the face and often are considered as one bone. They have been described as the architectural key of the face because all bones of the face except the mandible touch them. Together the maxillae form the floor of the orbit for each eye, the sides and lower walls of the nasal cavities, and the hard palate. The lower border of the maxilla supports the upper teeth. Each maxilla contains an air space called the maxillary sinus.

maxilla

One of a pair of joined facial bones that form the upper jaw, the hard palate, part of the wall of the cavity of the nose and part of the floor of each eye socket. The maxillae bear the upper teeth and each contains a cavity called the maxillary antrum or sinus.

maxilla

  1. (in vertebrates) one of a pair of joined bones forming the upper jaw, carrying all teeth except the incisors. The term is loosely used to denote the whole of the upper jaw.
  2. (in arthropods) that part of the mouthparts lying behind the jaws. See LABRUM and LABIUM.

Maxilla

The bone of the upper jaw which serves as a foundation of the face and supports the orbits.
