What is Calvaria?

Calvaria, also known as the skull or Calvarium, is the upper or superior part of the skull. It does not contain bones that make up the jaw or parts of the skull that form the face. Calvaria consists of four primary bone structures: frontal bones, two parietal bones, two time bones and occipital bones. It is a strong and hard structure that exists primarily to protect the brain from damage. Its shape differs from man to man; In some people, the sculcap has the shape of an oval, while in others it is almost perfectly circular. Two parietal bones together consist of sides and the upper part of the skull or the upper part of the skull, with the exception of the lower jaw. Two temporary bones are lower on the sides of the skull; They support temples on the sides of the face. The occipital bone is located on the lower back section of the skull. Together these bone structures form calvaria.

In infants, Calvaria is made up of a process known as intramembranous ossification,in which bones develop from tissue or membrane structure. Specifically, the word ossification refers to any process that includes a substance or structure changing to bones. The term intramembranky refers to the fact that a substance that turns into a bone is some form of connective tissue as opposed to cartilage. Many bones, including most of the lower part of the skull, are formed by endochondral ossification, which is the formation of cartilage bone. All different parts of Calvaria, however, begin as a soft and vulnerable membrane tissue that solidifies on the solid bones.

One of the features of Calvaria, which is present on the skulls of infants, is the presence of fontanels or soft spots. This allows the skull to bend and bend to some extent, allowing the child to fit through the birth canal. Many parents often fear that their child is a significant risk of damage due to the existence of soft fontanels. This is not the case, because the membranes that make up fontanels are very durable and strongly resistant to damage. There are a certain conditionnky, in which fontanels are extremely large; Sometimes they never turn to hard bones.
