What are maxilla and mandible?

What are maxilla and mandible?

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. This is similar to the mandible (lower jaw), which is also a fusion of two mandibular bones at the mandibular symphysis.

What is the maxilla anatomy?

Overview. The maxilla is the bone that forms your upper jaw. The right and left halves of the maxilla are irregularly shaped bones that fuse together in the middle of the skull, below the nose, in an area known as the intermaxillary suture. The maxilla is a major bone of the face.

What are the processes of maxilla?

[3] 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.

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. 1.149).

What type 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 is the mandible?

The mandible is the largest and strongest bone in the face. It forms the lower part of the jaw and part of the mouth. The mandible is the only moveable bone of the skull and is attached to muscles involved in chewing and other mouth movements. It also holds the bottom teeth in place. Also called lower jaw bone.

What’s the mandible called?

In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower teeth in place.

Where is mandible located?

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. The mandible is composed of the body and the ramus and is located inferior to the maxilla.

What is the anatomy 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. The mandible is composed of the body and the ramus and is located inferior to the maxilla. The body is a horizontally curved portion that creates the lower jawline.
