Genae. The cheek or side part of the head; the anterolateral part of an insect's head.

The cheeks form the lateral parts of the mouth. Externally, they have no precise limits: they are continuous, above, with the lower eyelid; below, they descend as far as the base of the jaw; before, they terminate at the alae nasi, and at the commissures of the lips; and behind, at the ear. Their thickness varies, according to the degree of fatness of the individual. They are formed of three layers; - one dermoid, another muscular, and the third mucous.
