Etymology: Latin "jugum" meant "yoke," the wooden crossbar that joined a pair of oxen, and the same root gave Latin "conjugalis," "of marriage," since marriage was seen as a yoking of two people. "Jugalis," the adjective formed from "jugum," therefore meant something like "pertaining to a yoke" or "paired." Its anatomical sense comes from the Latin phrase "os jugale," the "yoke bone," applied to the cheekbone because its arched shape bridges the gap between other bones of the face, much as a yoke links two animals. Anatomists in the 18th and 19th centuries took this Latin term into their work, and English adopted the adjective "jugal" for the same bone and its related structures. The word is a technical coinage in this sense, not a classical anatomical term, since Roman writers used different names for the cheek. "Jugular," the vein of the neck, comes from a different Latin word, "jugulum," meaning "collarbone" or "throat," and is only related to "jugalis" through the shared root "jug-."
