Processes of the Maxilla

Maxillae Consists of two bones fused together to form the maxillary arch

Maxilla Each bone of the maxillae is made up of a body and four processes

Frontal Process Strong plate, which projects upward, and backward, by the side of the nose, forming part of its lateral boundary.

Zygomatic Process The rough projection from the maxilla that articulates with the zygomatic bone.

Palatine Process 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.

Alveolar Process Thickened ridge of bone that contains the tooth sockets (dental alveoli) on bones that hold teeth. In humans, the tooth-bearing bones are the maxillae and the mandible.

Sinuses The term sinuses refers to hollow cavities all connected in the head. There are different types Paranasal sinuses are a group of four paired air filled pockets located in the head. Maxillary sinuses Frontal sinuses Ethmoid sinuses Sphenoid sinuses

Maxilla Tuberosity Posterior to the most distal molar of the maxillary dentition; a rounded roughened elevation

Palatine Sutures Midian Palatine Suture- Between the two palatine processes of the maxillae Transverse Palatine Suture - Between palatine bones and palatine process of the maxillae
