What attaches to zygomatic process?
The zygomatic arch is formed from parts of both the zygomatic bone and the temporal bone. The extension of the temporal bone is known specifically as the zygomatic process, and attaches directly to the similarly shaped process on the zygomatic bone.
What passes through the zygomatic arch?
The masseter muscle, important in chewing, arises from the lower edge of the arch; another major chewing muscle, the temporalis, passes through the arch. The zygomatic arch is particularly large and robust in herbivorous animals, including baboons and apes.
What bones connect to the zygomatic bone?
The facial area includes the zygomatic, or malar, bones (cheekbones), which join with the temporal and maxillary bones to form the zygomatic arch below the eye socket; the palatine bone; and the maxillary, or upper jaw, bones.
What does zygomatic bone articulate with?
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 zygomatic process of the maxilla articulates with?
Zygomatic process of maxilla In front it forms part of the anterior surface. Behind it is concave, and forms part of the infratemporal fossa. Above it is rough and serrated for articulation with the zygomatic bone.
Which facial bone articulates with teeth?
Mandible – The mandible is the jaw, and it is the bone into which the lower teeth are set. It articulates bilaterally with the temporal bone to form the temporomandibular joints. The mandible moves when the mouth is opened and closed.
What are the two processes that make up the zygomatic arch?
Description. The zygomatic arch (cheek bone) is formed by the zygomatic process of temporal bone and the temporal process of the zygomatic bone, the two being united by an oblique suture (zygomaticotemporal suture).
Does the zygomatic bone articulate with the mandible?
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….

What part of this bone articulates with the ulna?
The ulna articulates with the humerus at its most proximal point forming the elbow in a hinge joint. It is the trochlea of the humerus which sits in the semi-lunar notch of the ulna to form this joint.
What articulates with the temporal bone?
The temporal bone articulates anteriorly with the sphenoid bone, above with the parietal bone, and posteriorly with the occipital bone. The zygomatic process of the squamosal part has an anterior and a posterior root between which, on the lower surface, is located the mandibular canal.
What are the articulations of the maxilla?
Articulations. Each maxilla articulates with nine bones: two of the cranium: the frontal and ethmoid. seven of the face: the nasal, zygomatic, lacrimal, inferior nasal concha, palatine, vomer, and the adjacent fused maxilla.
Does maxilla articulate with sphenoid?
The single sphenoid bone articulates with the maxillary bones. The superior orbital fissure is an oblique space between the lesser and greater wings of the sphenoid. It communicates the orbit anteriorly with the middle cranial fossa posteriorly.
