상악, or the maxilla, is the upper jawbone in humans and many other animals. It plays a crucial role in forming the structure of the face, supporting the upper teeth, and facilitating functions like chewing and speaking. The maxilla also contains the maxillary sinuses, which are air-filled spaces that help with breathing and voice resonance. In addition to its structural importance, the 상악 connects with several other bones in the skull, including the nasal bones and zygomatic bones. This connection helps create the overall shape of the face. Proper alignment and health of the maxilla are essential for dental health and overall facial aesthetics.
