Os Zygomaticum, or the zygomatic bone, is a facial bone that forms the cheekbone and connects the temporal bone of the skull to the maxilla. Synonyms for this bone include the malar bone, jugal bone, and zygoma. The word zygoma comes from the Greek word "zygon", meaning yoke or bridge, which accurately describes the function of the zygomatic bone in bridging the temporal and maxillary bones. Other synonymic terms for this bone include the intermaxillary bone, infraorbital bone, and jugale. An understanding of these synonyms is important for medical professionals interested in the anatomy of the face, skull, and head.
