Frontal Bone, Posterior View

Description

Posteriorly oriented, the frontal bone is seen forming the anterior third of the calvaria, with its squamous part curving inferiorly toward the forehead and its posterior margin meeting the paired parietal bones at the coronal suture. Medially, the frontal bone approaches the sagittal suture at bregma where coronal and sagittal sutures intersect. Laterally, the frontal squama blends toward the temporal lines that would continue onto the parietals. Subtle relief corresponding to the superciliary region lies anteroinferior, even though the emphasis here is the posterior articulation. Attention to the coronal suture in this posterior view matters because it is a standard landmark for describing cranial vault growth, trauma patterns, and operative corridors. Coronal synostosis alters the normal relationship between the frontal and parietal bones, producing characteristic head shape changes and influencing planning for fronto-orbital advancement. In the adult male calvaria, the suture morphology also provides a stable reference when teaching how cranial vault fractures can propagate along suture lines rather than crossing them. A clean landmark. Course directors can drop this plate directly into gross anatomy and osteology teaching on the cranial sutures, fontanelles, and the bregma as a surface landmark. It also suits neurosurgical and craniofacial texts when illustrating coronal incision planning, burr hole referencing near the frontal region, and basic skull fracture orientation in radiology correlation.
