In the neurocranium these are the occipital bone, two temporal bones, two parietal bones, the sphenoid, ethmoid and frontal bones. The bones of the facial skeleton (14) are the vomer, two inferior nasal conchae, two nasal bones, two maxilla, two palatine bones, two zygomatic bones, and two lacrimal bones. This composite model also includes the upper teeth. The mandible and lower teeth are separate, animatable together, and included in the jaw.x3d model.'/>
