Zygomatic bone:
- The zygomatic bone is a paired bone that forms the cheek’s prominence and the orbit’s lateral wall. (1)
-
Lateral surface of zygomatic bone:
- The lateral surface of the zygomatic bone is convex and smooth. It forms the bone’s outer surface. (1)
-
Frontal process of zygomatic bone:
- The frontal process of the zygomatic bone is a thin, elongated bony projection that extends superior, taking part in the formation of the lateral wall of the orbit. (1)
-
Orbital tubercle:
- The orbital tubercle is a bony projection positioned on the frontal process of the zygomatic bone. It provides an attachment site for the orbicularis oculi muscle. (1)
-
Temporal process of zygomatic bone:
- The temporal process of zygomatic bone is a bony projection positioned on the lateral surface of the zygomatic bone. It articulates with the zygomatic process of the temporal bone. (1)
-
Zygomaticofacial foramen:
- The zygomaticofacial foramen is a small opening on the lateral surface of the zygomatic bone. (1)

-
Temporal surface of zygomatic bone:
- The temporal surface of the zygomatic bone is the inner surface of the bone. It faces the temporal bone and takes part in the formation of the temporal fossa. (1)
- Marginal tubercle:
-
Zygomaticotemporal foramen:
- The zygomaticotemporal foramen is a small opening or foramen located in the centre of the temporal surface. (1)

-
Orbital surface of zygomatic bone:
- The orbital surface of the zygomatic bone is a surface of the bone that takes part in the formation of the lateral wall of the orbit (1)
-
Zygomatico-orbital foramen:
- The zygomatic-orbital foramen is a small opening on the lateral wall of the orbit. (1)
