Fontana Anterior [F. Anterior, Pna; F. Frontalis (Major), Bna; F. Major, Jna; Syn.: P. Greater, P. Frontal, P. Diamond-shaped]

Anterior fontanelle [f. anterior, pna; f. frontalis (major), bna; f. major, jna; syn.: p. big, p. frontal, p. rhomboid] is an open place on the skull of a newborn baby, rhomboid-shaped, located between the frontal and parietal bones. It is also called the greater fontanel, frontal fontanel, or rhomboid fontanel. The anterior fontanel is necessary for childbirth, as it ensures the displacement of the bones of the baby’s skull during childbirth. After birth, it protects the baby's fragile brain. By the end of the first year of life, the anterior fontanelle usually closes, and by 2 years it is completely closed. The closure of the fontanel occurs due to the growth and closure of the bones of the skull.

The anterior fontanel is a fontanelle that is located between the frontal and parietal bones of the skull. It is diamond-shaped and closes in the second year of life, when the child's skull is already formed.

The anterior fontanel is one of five fontanelles that newborns have. All of them close during the first year of life, and only the anterior fontanel remains open the longest - until the second year of life. This is because it is located closest to the surface of the skull and is therefore the last to close.

After the closure of the anterior fontanel, the child's skull is fully formed, and any further changes in its size can only be associated with the growth of the skull bones over the following years.

In addition, the anterior fontanelle is one of the few fontanelles in children that can be felt through the skin and soft tissues of the skull. This can be useful for doctors if they want to check how well the fontanel is closed and whether there are any problems with its closure.

Thus, the anterior fontanelle plays an important role in the development of the child’s skull and is one of the last fontanelles to close in children. It closes in the second year of life and does not open again.
