The bones of the skull that cover the brain are called calvarium. Bones are connected by suture joint. The stitches are called stitched stitches. There are 6 spaces or Fontanels in the skull. Due to the presence of fontanel, the shape of the baby’s head changes during delivery and it comes out easily through the birth canal. By the age of two, the baby’s carotid bones are completely fused by the suchar joints. Carotid artery is made up of 8 hard and flat bones.
