Where are the zygomatic and maxillary bones located?

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 are the 2 zygomatic bones?

In the human skull, the zygomatic bone (cheekbone or malar bone) is a paired irregular bone which articulates with the maxilla, the temporal bone, the sphenoid bone and the frontal bone….

Does maxillary have a zygomatic process?

The zygomatic bone itself has four processes, namely the frontosphenoidal, orbital, maxillary and temporal processes.

How do you know if you have zygomatic bone?

The zygomatic bone (zygoma) is an irregularly shaped bone of the skull. It is often referred to as the cheekbone, and it comprises the prominence just below the lateral side of the orbit. The zygomatic bone is nearly quadrangular in shape and it features three surfaces, five borders and two processes.

What is an interesting fact about the zygomatic bone?

What happens if the zygomatic bone is damaged?

Patients may develop trismus (i.e. the inability to fully open the mouth) and have difficulty with chewing. There may also be bleeding through the nose, which depends on the severity of the injury. The cheekbone of these patients may be flattened due to the malar eminence being depressed.

Why is the zygomatic bone important?

The zygomatic bone functions as a structure which joins the bones of the face while protecting the arteries, nerves, veins, and organs which lie below the surface. The arches of the zygomatic bone provide a person’s cheeks with the structure to fill out the face.

How do I know if my zygomatic bone is broken?

Broken cheekbone/upper jaw (zygomatic maxillary fracture)

1. Flatness of the cheek.
2. Altered sensation underneath the eye on the affected side.
3. Problems with eyesight.
4. Pain with jaw movement.

What happens if a cat has a maxilla fracture?

The fractures can be impacted (pushed inward) resulting in disruption of the adjacent nasal cavity. Maxillary fractures infrequently result in instability. These fractures are usually “open” (bone exposed) and “comminuted” (multiple bone fragments).

What is the zygomatic process of the maxilla bone?

Zygomatic process of the maxilla bone. Together with the temporal process of the cheekbone, the zygomatic process of the temporal bone forms the zygomatic arch. This arch surrounds a large hollow that allows the temporal and masseter muscles to pass through to the lower jaw. It is this arch that gives the mid-face its shape.

Where is the maxilla located in a cat?

In-depth Information on Maxilla Fractures in Cats. The maxilla is actually a relatively thin and frail bone that forms the outer wall and floor of the nasal cavity (also known as the roof of the mouth or hard palate) and supports the upper canine, premolar and molar teeth on each side of the mouth.

Which is the most important bone in a cat?

The thick skull bone protects the cat’s delicate brain; other bones include the jawbones (mandible and maxilla), nasal bones, cheekbones and eye orbit. Neck and spine (vertebrae) – These bones run along the upper part of the cat’s body from the skull to the tail.
