Zygomatic boneIn the human skull, the zygomatic bone (from Ancient Greek: ζῠγόν, romanized: zugón, lit.'yoke'), also called cheekbone or malar bone, is a paired irregular bone, situated at the upper and lateral part of the face and forming part of the lateral wall and floor of the orbit, of the temporal fossa and the infratemporal fossa. It presents a malar and a temporal surface; four processes (the frontosphenoidal, orbital, maxillary, and temporal), and four borders.
Frontal boneIn the human skull, the frontal bone or sincipital bone is an unpaired bone which consists of two portions. These are the vertically oriented squamous part, and the horizontally oriented orbital part, making up the bony part of the forehead, part of the bony orbital cavity holding the eye, and part of the bony part of the nose respectively. The name comes from the Latin word frons (meaning "forehead"). StructureThe frontal bone is made up of two main parts.
Infratemporal fossaThe infratemporal fossa is an irregularly shaped cavity that is a part of the skull. It is situated below and medial to the zygomatic arch. It is not fully enclosed by bone in all directions. It contains superficial muscles, including the lower part of the temporalis muscle, the lateral pterygoid muscle, and the medial pterygoid muscle.
Process (anatomy)In anatomy, a process (Latin: processus) is a projection or outgrowth of tissue from a larger body. For instance, in a vertebra, a process may serve for muscle attachment and leverage (as in the case of the transverse and spinous processes), or to fit (forming a synovial joint), with another vertebra (as in the case of the articular processes). The word is also used at the microanatomic level, where cells can have processes such as cilia or pedicels.
SkullThe skull, or cranium, is typically a bony enclosure around the brain of a vertebrate. In some fish and amphibians, the skull is of cartilage. The skull is at the head end of the vertebrate. In a human, the skull comprises two prominent parts: the neurocranium and the facial skeleton, which evolved from the first pharyngeal arch.
Squamous part of temporal boneThe squamous part of the temporal bone, or temporal squama, forms the front and upper part of the temporal bone, and is scale-like, thin, and translucent. SurfacesIts outer surface is smooth and ; it affords attachment to the temporal muscle, and forms part of the temporal fossa; on its hinder part is a vertical groove for the middle temporal artery.
Zygomatic archIn anatomy, the zygomatic arch 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 cheekbone, the two being united by an oblique suture (the zygomaticotemporal suture); the tendon of the temporal muscle passes medial to (i.e. through the middle of) the arch, to gain insertion into the coronoid process of the mandible (jawbone).
ZygomaThe term zygoma generally refers to the zygomatic bone, a bone of the human skull that is commonly referred to as the cheekbone or malar bone, but it may also refer to: The zygomatic arch, a structure in the human skull formed primarily by parts of the zygomatic bone and the temporal boneThe zygomatic process, a bony protrusion of the human skull, mostly composed of the zygomatic bone but also contributed to by the frontal bone, temporal bone, and maxillaSee alsoZygoma implantZygoma reduction plasty This includes a list of related items that share the same name (or similar names).
JointA joint or articulation (or articular surface) is the connection made between bones, ossicles, or other hard structures in the body which link an animal's skeletal system into a functional whole. They are constructed to allow for different degrees and types of movement. Some joints, such as the knee, elbow, and shoulder, are self-lubricating, almost frictionless, and are able to withstand compression and maintain heavy loads while still executing smooth and precise movements.
BoneRigid organs of the skeleton of vertebratesA bone is a rigidorgan that constitutes part of the skeleton in most vertebrate animals. Bones protect the organs of the body, produce red and white blood cells, store minerals, help regulate acid-base homeostasis, provide structure and support for the body, and enable mobility and hearing. Bones come in a variety of shapes and sizes and have complex internal and external structures.
Greek languageIndo-European languageGreek (Modern Greek: ελληνικά, romanized: elliniká; Ancient Greek: ἑλληνική, romanized: hellēnikḗ) is an Indo-European language, constituting an independent Hellenic branch within the Indo-European language family.
Brow ridgeThe brow ridge, or supraorbital ridge known as superciliary arch in medicine, is a bony ridge located above the eye sockets of all primates and some other animals. In humans, the eyebrows are located on their lower margin. StructureThe brow ridge is a nodule or crest of bone situated on the frontal bone of the skull. It forms the separation between the forehead portion itself (the squama frontalis) and the roof of the eye sockets (the pars orbitalis).ζύγωμαRelated word or term.*As an Amazon Associate I earn from qualifying purchases.
