The orbital process 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.
The orbital surface presents medially by trochlear fovea and laterally by lacrimal fossa. [8] The floor (inferior wall) is formed by the orbital surface of maxilla, the orbital surface of zygomatic bone and the minute orbital process of palatine bone. Medially, near the orbital margin, is located the groove for nasolacrimal duct. Near the ...
The zygomaticofacial foramen is a small [citation needed] opening upon the lateral (facial) surface of the zygomatic bone near the bone's orbital border. It gives passage to the zygomaticofacial nerve, artery, and vein. It is often doubled; it is sometimes absent.
The zygomatico-orbital foramina are two canals in the skull, that allow nerves to pass through. The orifices are seen on the orbital process of the zygomatic bone. One of these canals opens into the temporal fossa, the other on the malar surface of the bone. The former transmits the zygomaticotemporal, the latter the zygomaticofacial nerve.
The zygomatic process of the temporal bone is a long, arched process projecting from the lower part of the squamous portion of the temporal bone. It articulates with the zygomatic bone . This process is at first directed lateralward, its two surfaces looking upward and downward; it then appears as if twisted inward upon itself, and runs forward ...
The inferior surface of each orbital plate is smooth and concave, and presents, laterally, under cover of the zygomatic process, a shallow depression, the lacrimal fossa, for the lacrimal gland; near the nasal part is a depression, the fovea trochlearis, or occasionally a small trochlear spine, for the attachment of the cartilaginous pulley of the obliquus oculi superior.
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 suture (the zygomaticotemporal suture); [1] the tendon of the temporal muscle ...
It consists of the zygomatic bone and the maxilla, on which it separates the anterior and the orbital surface of the body of the maxilla. Function It is ...
