26+ Coronal Suture Skull Images. The skull is a unique skeletal structure in several ways: This suture separates the frontal bone from both the left and right parietal bones.
It is formed by the union of the two parietal bones, those to either side of the top of the skull, with the frontal bone.
They are immovable, and fuse completely around the age coronal suture which fuses the frontal bone with the two parietal bones. The coronal suture is most commonly affected; Cartilage has been described underlying the coronal suture in mice of the c57bl/6 inbred strain. Sutures are just the joints of the skull.
