The term zygomatic derives from the Greek Ζυγόμα zygoma meaning "yoke". The zygomatic process is occasionally referred to as the zygoma, but this term usually refers to the zygomatic bone or occasionally the zygomatic arch.
Zygomatic process of frontal boneEdit

|Latin||processus zygomaticus ossis frontalis|
|Anatomical terms of bone|
The supraorbital margin of the frontal bone ends laterally in its zygomatic process, which is strong and prominent, and articulates with the zygomatic bone. The zygomatic process of the frontal bone extends from the frontal bone laterally and inferiorly.
Processes of the zygomatic boneEdit
The zygomatic bone itself has four processess, 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.
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.
