Zygomatic bone
Bone;Anatomical structure;Organic Object;Organic Thing
In the human skull, the zygomatic bone (cheekbone, malar bone) is a paired bone which articulates with the maxilla, the temporal bone, the sphenoid bone and the frontal bone. The zygomatic is homologous to the jugal bone of other tetrapods. It is situated at the upper and lateral part of the face and forms the prominence of the cheek, part of the lateral wall and floor of the orbit, and parts of the temporal and infratemporal fossa. It presents a malar and a temporal surface;four processes,...

Orbital process of the zygomatic bone
Anatomical structure;Organic Object;Organic Thing
The orbital process of the zygomatic bone is a thick, strong plate, projecting backward and medialward from the orbital margin.;Its antero-medial surface forms, by its junction with the orbital surface of the maxilla and with the great wing of the sphenoid, part of the floor and lateral wall of the orbit.;On it are seen the orifices of two canals, the zygomatico-orbital foramina, one of these canals opens into the temporal fossa, the other on the malar surface of the bone, the former transmits...

Zygomatic nerve
Nerve;Cranial nerve;Anatomical structure;Organic Object;Organic Thing
The zygomatic nerve (temporomalar nerve, orbital nerve) is a branch of the maxillary nerve (a trigeminal nerve branch) that enters the orbit and helps to supply the skin over the zygomatic and temporal bones. The zygomatic nerve is not to be confused with the zygomatic branches of the facial nerve.;The zygomatic nerve arises in the pterygopalatine fossa. It enters the orbit by the inferior orbital fissure, and divides at the back of that cavity into two branches, the zygomaticotemporal nerve...

Lateral process of the the zygomatic bone

The lateral process of the zygomatic bone (or malar) is convex and perforated near its center by a small aperture, the zygomaticofacial foramen, for the passage of the zygomaticofacial nerve and vessels;below this foramen is a slight elevation, which gives origin to the Zygomaticus.

Temporal process of the the zygomatic bone

The temporal surface of the zygomatic bone, directed backward and medialward, is concave, presenting medially a rough, triangular area, for articulation with the maxilla, and laterally a smooth, concave surface, the upper part of which forms the anterior boundary of the temporal fossa, the lower a part of the infratemporal fossa.;Near the center of this surface is the zygomaticotemporal foramen for the transmission of the zygomaticotemporal nerve.

Zygomatic arch
Anatomical structure;Organic Object;Organic Thing
The zygomatic arch or cheek bone is formed by the zygomatic process of 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 tendon of the Temporalis passes medial to the arch to gain insertion into the coronoid process of the mandible.;The term zygomatic derives from the Greek Ζυγόμα zygoma meaning "yoke". The zygomatic arch is...
