This entry is concerned with the word скула, referring to the zygomatic bone on the human face, and also to the part of that bone below the eye, and to the area of the cheek overlying this bone. For some speakers, this area extends all the way down
to the lower jaw; in fact, according to the dictionary by Владимир Даль, «Толковый словарь живого великорусского языка» published in 1880-1882, one of the meanings of the word скула is "jaw." This word does not refer to animals.
