In anatomy, the zygomatic arch (colloquially known as the 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 suture (the zygomaticotemporal suture); [1] the tendon ...
The zygomatic process forms an "L" in this picture. As a comparison, this is how the skull looks with almost all of the zygomatic process removed. The zygomatic processes (aka. malar) are three processes (protrusions) from other bones of the skull which each articulate with the zygomatic bone. The three processes are: [1]
The zygomatic process is a long, arched process projecting from the lower region of the squamous part and it articulates with the zygomatic bone. Posteroinferior to the squamous is the mastoid part. Fused with the squamous and mastoid parts and between the sphenoid and occipital bones lies the petrous part, which is shaped like a pyramid.
In 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.
The zygomaticotemporal suture (or temporozygomatic suture) is the cranial suture between the zygomatic bone and the temporal bone. [1] This is part of the zygomatic arch. [1] Movement at the suture decreases with development during aging. [1] It has a complex internal structure. [1]
Superior: Pair of temporal lines (superior and inferior temporal lines) that arch across the skull from the zygomatic process of the frontal bone to the supramastoid crest of the temporal bone [citation needed] Inferior: zygomatic arch laterally and by the infratemporal crest of the greater wing of the sphenoid medially. [citation needed]
ZMC complex fractures involve the lateral vertical buttress of the ZMC complex (lateral maxillary sinus and lateral orbital wall) and the upper transverse buttress (inferior orbital rim and floor, also including the zygomatic arch). Three of its four components are directly related to connections between the zygoma and the face.
In anatomy, the temporalis muscle, also known as the temporal muscle, is one of the muscles of mastication (chewing). It is a broad, fan-shaped convergent muscle on each side of the head that fills the temporal fossa, superior to the zygomatic arch so it covers much of the temporal bone. [1] Temporal refers to the head's temples.
