What is temporal process of zygomatic bone?
The zygomatic process of the temporal bone is a long, arched process projecting from the lower part of the squamous portion of the temporal bone. It articulates with the zygomatic bone.
What bones does the temporal bone articulate with?
The temporal bone articulates anteriorly with the sphenoid bone, above with the parietal bone, and posteriorly with the occipital bone.
Is the zygomatic arch part of the temporal bone?
In anatomy, the zygomatic arch, or cheek bone, is a part of the skull formed by the zygomatic process of the temporal bone (a bone extending forward from the side of the skull, over the opening of the ear) and the temporal process of the zygomatic bone (the side of the cheekbone), the two being united by an oblique …
Does the temporal bone articulate with the zygomatic bone?
The zygomatic bone articulates with the sphenoid bone, maxilla, frontal bone, and temporal bone to form the lateral wall of the floor of the orbit, part of the temporal and infratemporal fossa, and the prominence of the cheek.
What does the temporal process do?
n. The posterior projection of the zygomatic bone articulating with the zygomatic process of the temporal bone to form the zygomatic arch.
Is temporal bone a facial bone?
The joint between the mandible and the temporal bones of the neurocranium, known as the temporomandibular joint, forms the only non-sutured joint in the skull. Facial bones: There are fourteen facial bones. Some, like the lacrimal and nasal bones, are paired. Others, like the mandible and vomer, are singular.
Where is the temporal bone located?
the skull
The temporal bones are two major bones in the skull, or cranium. They help form the sides and base of the skull, where they protect the temporal lobe of the brain and surround the ear canal. The other major bones in the skull are: the two parietal bones that make up the top of the skull.
What is the process of temporal bone?
The temporal bone is ossified from eight centers, exclusive of those for the internal ear and the tympanic ossicles: one for the squama including the zygomatic process, one for the tympanic part, four for the petrous and mastoid parts, and two for the styloid process.
Does the zygomatic bone have a sinus?
It contains the largest of the paranasal sinuses, the maxillary sinus. To see the posterior part of the maxilla, we’ll remove the zygomatic arch. Here’s the back of the hollow part of the maxilla. Down here the maxilla is joined to the bone behind it, the sphenoid bone.
What is the squamous part of the temporal bone?
The squamous part is the anterior superior portion of the temporal bone that forms the lateral part of the middle cranial fossa. It has the appearance of a large flattened plate. Its external surface is smooth and slightly convex.
Where is the temporal area head?
It is located on the side of the head behind the eye between the forehead and the ear. The temporal muscle covers this area and is used during mastication.
What are the 3 parts of the temporal bone?
The temporal bones are divided into the squamosal, mastoid, tympanic, styloid, and petrous segments. Each articulates with the zygomatic bone (zygomaticotemporal suture), sphenoid bone (sphenosquamosal suture), parietal bone (parietosquamous suture), and occipital bone (occipitomastoid suture).
