The fontanelle, also commonly known as the fontanelle, is an important part of the newborn's head.
Since the skull of the newborn is not yet completely closed, the fontanelle becomes a distinct area.
Let's take a brief look at the structure and function of the fontanelle.
Neonatal skull specimens
First of all, the baby's fontanelle is divided into anterior fontanelle and posterior fontanelle.
The position of the anterior fontanelle is just above the head, resembling a diamond.
The posterior fontanelle is located at the back of the head, like a triangle.
Since there is no skull covering the fontanelle, we can observe the blood vessels under the scalp.
Under normal conditions, the fontanelle is very soft and can be touched slightly.

Then the role of the fontanelle is very large, when the baby is born, the skull that has not yet closed is squeezed, and the edges overlap, so that the volume of the fetal head is reduced, which can help the baby pass through the mother's narrow birth canal smoothly.
The fontanelle also allows space for the development of the head.
Baby's brain develops very fast and grows in size very quickly.
By the age of 1 year, the brain already weighs more than twice as much as it did at birth. However, the brain is constantly growing within the cranial cavity, and if the volume of the cranial cavity is fixed, then brain development is bound to be limited.
At this time, the existence of the fontanelle reserves space for brain development.

Therefore, the fontanelle is an important part of the newborn's head.
We must understand the features and functions of the fontanelle.
These are essential for the healthy growth of newborns.
Always pay attention to the condition of your baby's fontanelle and take reasonable care measures to ensure the healthy development of your baby.
