The maxilla (plural: maxillae /mækˈsɪliː/) in vertebrates is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones. In humans, the upper jaw includes the hard palate in the front of the mouth.

What type of bone is the maxilla and mandible?
Alveolar bone is that part of the maxilla and mandible which supports the teeth by forming the “other” attachment for fibres of the periodontal ligament (Fig. 1.148). It consists of two plates of cortical bone separated by spongy bone (Fig.
Is maxilla spongy bone?
The mandible possesses more compact bone, the maxilla more spongy; the resorption directions also differ (mandible: towards the oral aspect; maxilla: towards the vestibular).
What is the maxillary?
Maxillae are a pair of bones that form the dominant portion of the face. Functionally, the maxillae hold the tooth roots and form most of the nasal aperture and floor, most of the hard palate, and the floors of the orbits.
Is the maxilla bone paired?
The paired bones are the maxilla, palatine, zygomatic, nasal, lacrimal, and inferior nasal conchae bones. The unpaired bones are the vomer and mandible bones. Although classified with the brain-case bones, the ethmoid bone also contributes to the nasal septum and the walls of the nasal cavity and orbit.
What type of bone is alveolar bone?
Although the alveolar process is made up of compact bone, it may also be called the cribriform plate as it contains various holes where Volkmann canals pass from the alveolar bone and into the PDL. The alveolar bone proper is also called the bundle bone because of the Sharpey fibers.
What is the maxillary tuberosity?
The maxillary tuberosity is the most hind-most (distal) aspect of the upper jaw (maxilla), housing the sockets of the upper wisdom teeth, with its back (posterior) border curving upward and distally.
Which bone contains teeth?
Jaw, either of a pair of bones that form the framework of the mouth of vertebrate animals, usually containing teeth and including a movable lower jaw ( mandible ) and fixed upper jaw (maxilla).
Why is it called maxilla?
It provides critical bone structure to the skull and defines the face, for example. Since it houses the upper teeth and forms a portion of the jaw, the maxilla is necessary for the process of mastication (chewing) and speaking.
What bone is inferior to the maxilla?
The maxilla articulates with numerous bones: superiorly with the frontal bone, posteriorly with the sphenoid bone, palatine and lacrimal bones and ethmoid bone, medially with the nasal bone, vomer, inferior nasal concha and laterally with the zygomatic bone.
Is the maxilla one or two bones?
1 Anatomy. Maxillae are a pair of bones that form the dominant portion of the face. Functionally, the maxillae hold the tooth roots and form most of the nasal aperture and floor, most of the hard palate, and the floors of the orbits.
What kind of joint attaches the maxilla to the palatine bone?
The two plates form the posterior part of the hard palate and the floor of the nasal cavity; anteriorly, they join with the maxillae. The two horizontal plates articulate with each other at the posterior part of the median palatine suture and more anteriorly with the maxillae at the transverse palatine suture.
Which bones does the maxilla articulate with?
 The maxilla connects with surrounding facial structures through four processes: alveolar, frontal, zygomatic and palatine. It articulates superiorly with the frontal bone, the zygomatic bone laterally, palatine bone posteriorly and with the upper teeth through the alveolar process inferiorly.
Is maxillary upper or lower?
The term, “maxillary”, is given to teeth in the upper jaw and “mandibular” to those in the lower jaw. There are four classes of teeth: incisors, canines, premolars, and molars.
