What are the lines on skulls?
The two suture lines seen on the top of the skull are the coronal and sagittal sutures. The coronal suture runs from side to side across the skull, within the coronal plane of section (see Figure 3). It joins the frontal bone to the right and left parietal bones.
What are the lines called where the skull fuses together?
The skull of an infant or young child is made up of bony plates that allow for growth of the skull. The borders where these plates intersect are called sutures or suture lines. In an infant only a few minutes old, the pressure from delivery compresses the head.
What age does the skull fuse?
Around two years of age, a child’s skull bones begin to join together because the sutures become bone. When this occurs, the suture is said to “close.” In a baby with craniosynostosis, one or more of the sutures closes too early. This can limit or slow the growth of the baby’s brain.
Is it normal to have lines in skull?

The rare disease causes a thickening of the skin on the top of the head which leads to the curves and folds of the scalp. “There are two forms of it (CVG).
How long does it take for the skull to fully develop?
When babies are born their skulls are soft, which helps them pass through the birth canal. It can take 9-18 months before a baby’s skull is fully formed. During this time some babies develop positional plagiocephaly. This means that there is a flat area on the back or side of the head.
