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.
Is the maxilla one bone or two?
Anatomical terms of bone 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.
Is the maxilla a paired bone?
Note that the maxilla may look like a single bone but is truly paired forming a delicate suture in the middle line known as the median palatine (or intermaxillary) suture. Furthermore the bone comes in contact with the septal and nasal cartilages.
Which 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.Is the maxilla the cheek bone?

Is maxilla and maxillary the same thing?
As nouns the difference between maxillary and maxilla is that maxillary is the jawbone while maxilla is either of the two bones that together form the upper jaw.
Is maxilla same as maxillary bone?
The two maxilla or maxillary bones (maxillae, plural) form the upper jaw (L., mala, jaw). 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.
Where is the maxillary bone located?
The maxilla is a bone which helps to make up the skull. It is specifically located in the mid face, forms the upper jaw, separates the nasal and oral cavities, and contains the maxillary sinuses (located on each side of the nose.What bones does maxilla articulate with?
[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.
Is the maxilla paired or unpaired?The paired bones are the maxilla, palatine, zygomatic, nasal, lacrimal, and inferior nasal conchae bones. The unpaired bones are the vomer and mandible bones.
Article first time published onIs maxilla a irregular bone?
The irregular bones are: the vertebrae, sacrum, coccyx, temporal, sphenoid, ethmoid, zygomatic, maxilla, mandible, palatine, inferior nasal concha, and hyoid.
What is the cheek bone called?
zygomatic bone, also called cheekbone, or malar bone, diamond-shaped bone below and lateral to the orbit, or eye socket, at the widest part of the cheek. It adjoins the frontal bone at the outer edge of the orbit and the sphenoid and maxilla within the orbit.
What is the name of the cheek bone?
The three bony structures that help form the cheek are the zygomatic bone, the maxilla bone, and the mandibular bone. The zygomatic bone and the maxilla bone makes up the superior bony region of the cheek. The maxilla bone also makes the medial bony region of the cheek.
Where is vomer bone?
The vomer is a small, thin, plow-shaped, midline bone that occupies and divides the nasal cavity. It articulates inferiorly on the midline with the maxillae and the palatines, superiorly with the sphenoid via its wings, and anterosuperiorly with the ethmoid.
What is mandible bone?
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.
Does the mandible follow the maxilla?
Our lower jaw, the mandible, grows by appositional growth. As the mandible follows the maxilla forward, new bone is deposited at the distal, the back end, of the jaw. Let’s start with the basics.
What joins the palatine bone to the maxilla?
The median palatine suture connects the horizontal plates of the palatines. It is the posterior continuation of the intermaxillary suture. The transverse palatine suture adheres the palatine process of the maxillary bone to the palatine bone.
What are facial bones?
The primary bones of the face are the mandible, maxilla, frontal bone, nasal bones, and zygoma. Facial bone anatomy is complex, yet elegant, in its suitability to serve a multitude of functions.
Which bones contain alveolar processes?
The alveolar bone is located on the jaw bones which hold the teeth. In humans, these bones that contain the teeth are the maxilla and the mandible. The curved portion of each alveolar process on the jaw is the alveolar arch.
What are pneumatic bones?
Pneumatic bones are those bones which contain an air filled cavity within them. In humans, they are seen in relation to the the nasal cavity – they enclose the paranasal sinuses. Pneumatic bones are – maxilla, frontal bone, sphenoid and ethmoid.
What bones are sesamoid bones?
Sesamoid bones are bones embedded in tendons. These small, round bones are commonly found in the tendons of the hands, knees, and feet. Sesamoid bones function to protect tendons from stress and wear. The patella, commonly referred to as the kneecap, is an example of a sesamoid bone.
Are the phalanges short bones?
The short bones include all of the metacarpals and phalanges in the hands, and the metatarsals and phalanges in the feet. … They include the bones in the vertebral column, the carpal bones in the hands, tarsal bones in the feet, and the patella (kneecap).
What is the frontal process of maxilla?
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 two bones make up the cheek?
- The zygomatic bones (Gr., zygoma – yoke) are two facial bones that form the cheeks and the lateral walls of the orbits.
- They are also commonly referred to a as the cheekbones or malar bones (L., mala – the cheek).
What does zygomatic process of maxilla mean?
The zygomatic process of the maxilla (malar process) 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. … Above it is rough and serrated for articulation with the zygomatic bone.
How many cheek bones are there?
Structure. In the human skull, the facial skeleton consists of fourteen bones in the face: Inferior turbinal (2)
Why is it called zygomatic bone?
The zygomatic bone is also known as the zygomatic arch, the zygoma, the malar bone, the cheek bone and the yoke bone. The word “zygomatic” comes from the Greek “zygon” meaning a yoke or crossbar by which two draft animals such as oxen could be hitched to a plow or wagon.
What 2 bones make up the zygomatic arch?
The cranial portion of the zygomatic arch is formed by the zygomatic bone, and the caudal portion is formed by the zygomatic process of the temporal bone. The zygomatic arch forms the ventral and lateral rim of the orbit.
Is the vomer a cranial bone?
Located in the center of the nasal cavity, the vomer is a thin, unpaired bone of the face and skull (cranium).
What kind of bone is the vomer?

What is the maxillary crest?
This strip of bone is called the maxillary crest; it articulates in front with the quadrangular cartilage, and at the back with the vomer. The maxillary crest is described in the anatomy of the nasal septum as having a maxillary component and a palatine component.
