Answer

Ossification of the cranial vault starts in the central region of each cranial bone and extends outward toward the cranial sutures.

See the list below:

  • The coronal suture separates the 2 frontal bones from the parietal bones.

  • The metopic suture separates the frontal bones.

  • The sagittal suture separates the 2 parietal bones.

  • The lambdoid suture separates the occipital bone from the 2 parietal bones.

  • The primary factor that keeps sutures open is ongoing brain growth.

  • Normal skull growth occurs perpendicular to each suture.
