In non-mammalian vertebrates, the zygomatic bone is referred to as the jugal bone, since these animals have no zygomatic arch. It is found in most reptiles, amphibians, and birds. It is connected to the quadratojugal and maxilla, as well as other bones, which may vary by species. This bone is considered key in the determination of general traits of the skull, as in the case of creatures, such as dinosaurs in paleontology, whose entire skull has not been found. In coelacanths"
"Temporal bone The temporal bones are situated at the sides and base of the skull, and lateral to the temporal lobes of the cerebral cortex. The temporal bones are overlaid by the sides of the head known as the temples, and house the structures of the ears. The lower seven cranial nerves and the major vessels to and from the brain traverse the temporal bone. The temporal bone consists of four parts— the squamous, mastoid, petrous and tympanic parts. The squamous part is the largest and most superiorly positioned relative to the rest of the bone. The zygomatic process is"

Because of the sturdy anchorage achievable in the dense bone of the zygomatic region, and the wide stress distribution achieved on these tilted implants, a prosthesis can often be immediately placed at the time of surgery . The Zygoma implant is available in lengths ranging from 30 to 52.5 mm. The head of the zygoma implant is engineered to allow prosthesis attachment at a 45-degree angle to the long axis of the implant. Zygomatic"

The term ""zygomatic"" derives from the Greek ζύγωμα zygōma, meaning ""bolt, bar"", derived from ζυγο-, ""yoke, join"". The Greek word was already used with this anatomical sense by Galen (2.437, 746) in the 2nd century AD. The zygomatic arch is occasionally referred to as the zygoma, but this term usually refers to the zygomatic bone or occasionally the zygomatic process.

It is derived from the zygomatic nerve, a branch of the maxillary nerve. It runs along the lateral wall of the orbit in a groove in the zygomatic bone, receives a branch of communication from the lacrimal nerve, and passes through the zygomaticotemporal foramen in the zygomatic bone to enter the temporal fossa. It ascends between the bone and the substance of the temporalis muscle, pierces the temporal fascia about 2.5 cm. above the zygomatic arch, and is distributed to the skin of"

This bone is considered key in the determination of general traits of the skull, in the case of creatures, as with dinosaurs in paleontology, whose entire skull has not been found. The jugal bone forms the cheek area in dinosaurs, and is part of the series of bones termed the circumorbital series, as they define the"

They may be used when maxillary bone quality or quantity is inadequate for the placement of regular dental implants. Inadequate maxillary bone volume may be due to bone resorption as well as to pneumatization of the maxillary sinus or to a combination of both. The minimal bone height for a standard implant placement in the posterior region of the upper jaw should be about 10 mm to ensure acceptable implant"

"is the place in the human body where the most irregular bones can be found. There are, in all, 33 irregular bones found here. The irregular bones are: the vertebrae, sacrum, coccyx, temporal, sphenoid, ethmoid, zygomatic, maxilla, mandible, palatine, inferior nasal concha, and hyoid. Irregular bone The irregular bones are bones which, from their peculiar form, cannot be grouped as long, short, flat or sesamoid bones. Irregular bones serve various purposes in the body, such as protection of nervous tissue (such as the vertebrae protect the spinal cord), affording multiple anchor points for skeletal muscle attachment (as with the sacrum),"
"Squamosal bone The squamosal is a bone of the head of higher vertebrates. It is the principal component of the cheek region in the skull, lying below the temporal series and otic notch and bounded anteriorly by the postorbital. Posteriorly, the squamosal articulates with the posterior elements of the palatal complex, namely the quadrate and pterygoid. The squamosal is bordered anteroventrally by the jugal and ventrally by the quadratojugal. In many mammals, including humans, it fuses with the periotic bone and the auditory bulla to form the temporal bone, then referred to as the squama temporalis. In synapsids (mammal-like reptiles)"
