About
颌 (hé) is the simplified form of 頜, a phono-semantic compound used in anatomical and biological contexts to designate the jaw, jawbone, or bony framework of the mouth. The traditional character combines the radical 頁 (yè), meaning 'head' or 'face', with the phonetic component 合 (hé). Although 合 independently means 'to close', here it solely provides the sound. The radical 頁 was later reduced to 页, yielding the modern 颌. The simplified form is now standard and ties the character to the cranial region of humans and animals. This term is common in medical, dental, and zoological terminology for the skeletal structures of the mouth.
