Parietal Bone of a Human Male as, Posterior View

Description

Posteriorly oriented, the parietal bone (os parietale) forms the dominant expanse of the skullcap (calvaria), meeting its contralateral partner at the midline along the sagittal suture. Superolaterally, the paired parietals curve toward the parietal eminence, while inferior margins descend toward the squamous region where the parietal would articulate with the temporal bone at the squamous suture. The lambdoid suture typically frames the posteroinferior border against the occipital bone, and parietal foramina, when present, lie near the posterior third of the sagittal suture. Clean landmarks. For teaching cranial sutures, a posterior view is where the sagittal and lambdoid sutures read most clearly as a continuous map, and where you can discuss normal interdigitation versus diastasis. This is the orientation clinicians have in mind when assessing occipitoparietal trauma patterns, including linear fractures that cross suture lines, and when recognizing sagittal suture synostosis (scaphocephaly), where early fusion alters biparietal width and skull contour. It also supports surgical planning for posterior cranial approaches, where burr holes and craniotomy cuts must respect suture-adjacent venous anatomy, including emissary veins that may traverse parietal foramina to the superior sagittal sinus. Use this illustration in gross anatomy and osteology curricula to anchor midline calvarial landmarks, and in radiology or neurosurgery teaching files to pair with posterior skull radiographs or CT bone windows when discussing suture anatomy and fracture trajectories. Suitable for medical textbooks, trauma education modules, and patient-facing explanations of craniosynostosis patterns. Anatomical accuracy verified by SciePro's Medical Advisory Board.
