What are the processes of maxilla?
Each maxilla has four processes (frontal, zygomatic, alveolar, and palatine) and helps form the orbit, roof of the mouth, and the lateral walls of the nasal cavity.
What are features of the maxillary bone?
Each maxillary bone has the shape of a pyramid, it’s base adjacent to the nasal cavity, its apex being the zygomatic process, and its body constituting the maxillary sinus. [3] The maxilla connects with surrounding facial structures through four processes: alveolar, frontal, zygomatic and palatine.
What is the function of the mandible and maxilla?
Along with the upper jaw or maxilla, the mandible serves an essential structural and protective function. Not only do important nerves and muscles run through this bone and emerge from it, but it’s also what houses the lower set of teeth.
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.
What landmark is formed by the maxilla?
In humans, the upper jaw includes the hard palate in the front of the mouth. The two maxillary bones are fused at the intermaxillary suture, forming the anterior nasal spine….

How is maxilla called cavity of the body?
The body is somewhat pyramidal in shape, and contains a large cavity, the maxillary sinus (antrum of Highmore).
What kind of bone is maxilla?
The answer to the question, “What type of bone is the maxilla bone?” is simple – it is an irregular facial bone. You can refer to the maxilla bone as a single unit or as two paired but fused bones.
What type of bone is the maxilla and mandible?
Alveolar bone
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.
What is the main function of the mandible?
The mandible is the largest bone in the human skull. It holds the lower teeth in place, it assists in mastication and forms the lower jawline.
What are mandibles used for?
The mandible (from Latin: mandibula or mandĭbŭ-lum, a jaw) of an arthropod is a pair of mouthparts used either for biting or cutting and holding food. Mandibles are often simply called jaws. Mandibles are present in the extant subphyla Myriapoda (millipedes and others), Crustacea and Hexapoda (insects etc.).
Is maxilla a cranial bone?
The skull bones that contain foramina include the frontal, ethmoid, sphenoid, maxilla, palatine, temporal, and occipital.
What is meant by frontal process of maxilla?
Anatomical terms of bone The frontal process of maxilla is a strong plate, which projects upward, medialward, and backward from the maxilla, forming part of the lateral boundary of the nose.
What does maxilla mean in Latin?
Meanwhile, maxilla in “maxillary” is derived from the Latin word “mala,” which means “cheek.” The Latin word macerare also means “to chew,” and this potentially was the foundation for the term “maxilla” as well. A fracture of the maxillary tuberosity is an important medical issue.
What is the common name for the maxilla?
The maxilla, also known as the upper jaw, is a vital viscerocranium structure of the skull. It is involved in the formation of the orbit, nose and palate, holds the upper teeth and plays an important role for mastication and communication. Nov 22 2019
What is the common for maxilla bone?
Malo and maxillary bone fractures (malo refers to the cheekbone/zygomatic bone) are relatively common. They are usually caused by falls, motor vehicle accidents, and violent assaults. Up to 25% of facial fractures involve the maxillary bone. It is centrally located and especially assaults tend to concentrate on this part of the face.
Does the mandible and maxilla articulate?
When the skull is observed purely as a bony structure, there is nothing anatomically holding the rest of the skull and the mandible together. This bone is also known as the lower jaw and it articulates dentally with the upper jaw or the maxilla in the viscerocranium via the teeth when the mouth is closed.
