- Zygomatic process
Zygomatic process is a protrusion from the rest of the
skull, like the 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, maxillaand temporal bone, which therefore form:
Zygomatic process of frontal bone
Zygomatic process of maxilla
Zygomatic process of temporal bone
The zygomatic process is actually the entity of several processes, namely the frontosphenoidal, orbital, maxillary and temporal processes.
The "frontosphenoidal process" is thick and serrated. The
cranial suturebetween 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.
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.
