Zygomatic process 5170739 213429509 2008-05-19T08:47:27Z Gracillis 4775916 [[th:ส่วนยื่นจดกระดูกโหนกแก้ม]] [[Image:Gray164.png|thumb|right|300px|The Zygomatic process forms an "L" in this picture.]] '''Zygomatic process''' is a protrusion from the rest of the [[skull]], like the [[Bumper (automobile)|bumper]] of a car. Most of it belongs to the [[zygomatic bone]], and could therefore be called the zygomatic process of the zygomatic bone. However, there are other bones contributing to it too, namely the [[frontal bone]], [[maxilla]] and [[temporal bone]], which therefore form: * [[Zygomatic process of frontal bone]] * [[Zygomatic process of maxilla]] * [[Zygomatic process of temporal bone]] ==Processes== The zygomatic process is actually the entity of several [[Process (anatomy)|process]]es, namely the frontosphenoidal, orbital, maxillary and temporal processes. The ''frontosphenoidal process'' is thick and serrated. The [[cranial suture]] between the frontal and zygomatic bone is found here. On its orbital surface, just within the orbital margin and about 11 mm below the zygomaticofrontal suture is a tubercle of varying size and form, but present in 95 per cent of skulls (Whitnall 43). This tubercle isn't seen in the picture. [[Image:Gray189.png|thumb|200px|As a comparison, this is how the skull looks like with almost all of the zygomatic process removed]] The ''[[orbital process]]'' is a thick, strong plate, projecting backward and medialward from the orbital margin. It is the gloomy area beneath the lac(rimal) and ethmoidal bones in the image. The ''maxillary process'' presents a rough, triangular surface which articulates with the maxilla. It is the area below "zygomatic" in the image. The ''temporal process'', long, narrow, and serrated, articulates with the [[zygomatic process of the temporal]]. It is the process to the right of "zygomatic" in the image. [[Category:Skull]] [[th:ส่วนยื่นจดกระดูกโหนกแก้ม]]
