The document discusses the bones that make up the human skull. It is divided into two main parts: the calvaria or brain box, and the facial skeleton. The calvaria contains 14 paired and unpaired bones that form the upper part of the cranium protecting the brain, including the frontal, occipital, sphenoid, and ethmoid bones. The facial skeleton contains 14 additional bones, such as the paired maxilla, zygomatic, nasal, and lacrimal bones, as well as the unpaired mandible and vomer. Diagrams are provided showing the bones from different views and the skull's sutures where bones connect.
