The frontal bone forms the superior part of the bony orbits or eye sockets. The cranial bones, especially those forming the cranial base, connect the lower part of the skull to the rest of the body through articulations with the facial bones, the mandible (temporomandibular joint or TMJ), and 1st cervical vertebra.
The bones in the canial roof articulate with each other via sutures, with the most significant sutures of the human skull being formed in this region. The frontal, occipital and parietal bones form the cranial roof, while all six bones contribute to the cranial base. The cranium is divided into the cranial roof or skullcap and the cranial base. The 8 (2 paired and 4 unpaired) bones forming the cranium are called the cranial bones. The hollow space taken up by the brain is called the cranial cavity. It is the uppermost part of the skull that encircles and protects the brain, as well as the cerebral vasculature and meninges.
Names, Anatomy, and Structure of the Bones in the Skull Neurocranium The skull is divided into the neurocranium and the facial skeleton. There are 29 bones (including the hyoid and middle ear bones) that comprise the skull and give shape to the head.
The skull is one of the most vital bony structures of the human body, as it houses and protects the most important organs, including the brain.
