About
Corresponding to the traditional form 顎, the character 颚 is a phono-semantic compound. The radical 页 on the right, associated with the head or facial features, provides the semantic category, while the component 咢 on the left acts as the phonetic element. It denotes the jaw or palate, the bony structures forming the mouth framework that house the teeth in humans and many animals. The term is primarily used in anatomical, medical, and zoological contexts to refer to the upper and lower mandibles, as well as the chewing apparatus in insects and other organisms. Given its specific technical sense, it is seldom used metaphorically, applying directly to the physical structures involved in biting, chewing, and vocalization.
