Which bones are part of the facial structure?

The answer focusing on nasal bones, maxilla, mandible, and zygomatic bones is correct because these bones are specifically classified as part of the facial skeleton, which supports the structure of the face. The nasal bones form the bridge of the nose, while the maxilla and mandible create the upper and lower jaws, respectively. The zygomatic bones, often referred to as the cheekbones, contribute to the prominence of the cheeks and help shape the orbit of the eye. Collectively, these bones play significant roles in both the aesthetic and functional aspects of the face, including supporting facial muscles and enabling activities such as chewing and speaking.

Other choices include bones that are not part of the facial structure. For instance, the frontal and parietal bones are components of the cranial skeleton, which encases the brain, while the clavicle and scapula are part of the shoulder girdle. Hence, while they are important for overall anatomy, they do not contribute to the formation of the face itself.
