Frontal, zygomatic, lacrimal, nasal, maxilla, mandible, temporal, occipital, sphenoid, and parietal. Let's look over each of the colored areas of the skull below to locate the 10 major bones. Frontal, the frontal bones form the forehead. Zygomatic, the zygomatic bone forms the cheeks. Lacrimal, the lacrimal are the small fragile bones that form the front inner walls of the eye sockets. Nasal, the nasal bone forms the bridge of the nose. Maxilla, the maxilla bones form the upper jaw. Mandible, the mandible is the lower jaw bone and is the largest and strongest bone of the face.
