The paired parietal bones form the roof and sides of the cranium (Figure 8-1). The parietal bones articulate with each other at the midline in the sagittal suture, with the occipital bone posteriorly in the lambdoid suture, and with the frontal bone anteriorly at the coronal suture.

The manubrium is the superior part of the sternum lying at the level of T3-T4 vertebrae. It forms the superior wall of the anterior mediastinum and its superior border also contributes to the superior thoracic aperture (thoracic inlet).
