The maxilla is a paired bone - the two maxillae unite with each other at the intermaxillary suture. The maxilla consists of: [5] Inferior surface of maxilla. The body of the maxilla: pyramid-shaped; has an orbital, a nasal, an infratemporal, and a facial surface; contains the maxillary sinus. Four processes: the zygomatic process; the frontal ...
It is the largest air sinus in the body. [1] [3] It has a mean volume of about 10 ml. [1] [verification needed] It is situated within the body of the maxilla, [1] [3] [4] but may extend into its zygomatic and alveolar processes when large. It is pyramid-shaped, with the apex at the maxillary zygomatic process, and the base represented by the ...
Each maxilla consists of two parts, the proximal cardo (plural cardines), and distal stipes (plural stipites). At the apex of each stipes are two lobes, the inner lacinia and outer galea (plurals laciniae and galeae). At the outer margin, the typical galea is a cupped or scoop-like structure, located over the outer edge of the labium.
Jaw. Human lower jaw viewed from the left. The jaws are a pair of opposable articulated structures at the entrance of the mouth, typically used for grasping and manipulating food. The term jaws is also broadly applied to the whole of the structures constituting the vault of the mouth and serving to open and close it and is part of the body plan ...
The zygomatic process of the maxilla [2] is a rough triangular eminence, situated at the angle of separation of the anterior, zygomatic, and orbital surfaces. In front it forms part of the anterior surface. Behind it is concave, and forms part of the infratemporal fossa. Above it is rough and serrated for articulation with the zygomatic bone.
Anatomical terms of bone. [edit on Wikidata] The alveolar process (/ ælˈviːələr, ˌælviˈoʊlər, ˈælviələr /) [1] is the portion of bone containing the tooth sockets on the jaw bones (in humans, the maxilla and the mandible). The alveolar process is covered by gums within the mouth, terminating roughly along the line of the ...
In human anatomy of the mouth, the palatine process of maxilla (palatal process), is a thick, horizontal process of the maxilla. It forms the anterior three quarters of the hard palate, the horizontal plate of the palatine bone making up the rest. It is the most important bone in the midface. It provides structural support for the viscerocranium.
FMA. 52894. Anatomical terms of bone. [edit on Wikidata] The frontal process of the maxilla is a strong plate, which projects upward, medialward, and backward from the maxilla, forming part of the lateral boundary of the nose. Its lateral surface is smooth, continuous with the anterior surface of the body, and gives attachment to the quadratus ...
