The frontal bone, parietal bones, and occipital bone are seen in a superior view of the skull (Fig. 8.21). These bones make up the superior part of the calvaria or the calva (skullcap).
In an anterior to posterior direction:
The unpaired frontal bone articulates with the paired parietal bones at the coronal suture.
The two parietal bones articulate with each other in the midline at the sagittal suture.
