Zygomatic bone

The zygomatic bone is relatively small but structurally significant. It transmits the pressure applied to the zygomatic region toward three otherwise unconnected bones – the maxilla, the frontal, and the temporal bone. The zygomatic bones also contain the system of canals for the branches of the zygomatic nerve.
