What is a malar process?
Anatomical terms of bone. 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. Behind it is concave, and forms part of the infratemporal fossa.
What is zygomatic process?
Medical Definition of zygomatic process : any of several bony processes that articulate with the zygomatic bone: as. a : a long slender process of the temporal bone helping to form the zygomatic arch. b : a narrow process of the frontal bone articulating with the zygomatic bone.
What is the zygomatic bone?
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.
Why is it called the zygomatic process?
Specifically, it is the main protrusion of bone that forms the prominence of the upper cheek, the cheekbone. This process is called the zygomatic process because the zygomatic bone forms the majority of it, but the maxilla, temporal and frontal bones also contribute to the protrusion.
What is the root of zygoma?
The zygomatic process of the temporal arises by two roots: an anterior, directed inward in front of the mandibular fossa, where it expands to form the articular tubercle. a posterior, which runs backward above the external acoustic meatus and is continuous with the supramastoid crest.
What is the function of cheekbones?
They are important contributors to mastication or chewing, providing an attachment point for the masseter muscle – a jaw adductor that closes the jaw. In addition, the cheekbone contributes to the structure of the eye orbits and our ability to articulate.
Why is the zygomatic process important?
The zygomatic arch plays a critical role in the mammalian masticatory system. Formed by the union of the zygomatic process of the temporal bone and the temporal process of the zygomatic bone, it is from this beam-like structure that the masseter muscle, a major jaw adductor, originates.
What is cheek bone?
(CHEEK-bone) One of a pair of bones on each upper side of the face that forms the cheek and part of the eye socket. The cheekbones help give shape and structure to the face and are connected to the jaw and bones near the ears, forehead, and skull.
Where is left medial zygoma?
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.
What is zygomatic crest?
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 …
What are the two bones that form the zygomatic arch?
zygomatic arch, bridge of bone extending from the temporal bone at the side of the head around to the maxilla (upper jawbone) in front and including the zygomatic (cheek) bone as a major portion.
Are cheekbones real?
Cheekbones, also called zygomatic bones, are part of the human skull, located underneath the eye socket. Cheekbones extend out from the face, creating the structure of the cheeks that holds food inside the mouth while you chew.

What is the zygomatic process?
zygoma (zīgō´mə), n 1. a long, slender process of the temporal bone, arising from the lower part of the squamous portion of the temporal bone and passing forward horizontally to join with the malar or zygomatic bone. 2. the zygomatic or malar bone that forms the prominence of the cheek.
What is another name for the zygomatic arch?
Synonym (s): arcus zygomaticus, cheek bone (2) , malar arch, zygoma (2) . Quadrilateral bone that forms prominence of cheek, lateral wall and margin of orbit, and anterior two thirds of zygomatic arch; it articulates with the frontal, sphenoid, temporal, and maxillary bones.
