Bone fontanelles

The fontanel bone is a paired bone that is located at the base of the skull and is part of the occipital bone. It consists of two parts: front and back. The front part of the bone is called the frontal, and the back is called the occipital.

The fontanelle bone has the shape of a pyramid with a truncated base. At the top of the bone there is a fontanel - a small hole through which the two halves of the skull are connected. The fontanelle closes during the first year of a child's life, after which it becomes immobile.

The function of the fontanelle bone is that it provides mobility to the skull and allows it to grow and develop. In addition, thanks to the fontanel, fluids are exchanged between the brain and cerebrospinal fluid, which ensures the normal functioning of the nervous system.
