The skull is the bony structure that is responsible for covering and protecting the brain (the set of various organs and structures that are included in the nervous system, such as the brain, the cerebellum and the medulla oblongata).

Eight bones form the box of the human skull, whose thickness varies according to the person; their names are as follows: occipital, frontal, ethmoid, sphenoid, two parietal, and two temporal. It is important to highlight that in some cases the existence of sutural bones is also recorded.

There are several denominations that are equivalent or similar to the notion of skull. The skull is also often referred to as the head skeleton, bony head, or skull, depending on the context.

According to, the bony structure that contains the brain is called the skull.

Skull function

The function of the skull is very important as it provides protection to the brain, a very sensitive organ that is essential for life.

What the skull does is protect the brain from blows and other damage, although the bony box can also be affected by trauma.

Skull is often used as a synonym for skull.


A head injury, in fact, is caused by a strong blow to the cranial region that causes neurological problems. This is a physical injury that causes bleeding or bruising in certain regions of the brainstem, cerebellum, or cerebrum.

Loss of consciousness or memory, balance problems, speech difficulties, and decreased vision are some symptoms of a head injury.

To avoid these disorders, it is important to protect the skull with a helmet when doing certain risky activities (such as working on a construction site, where it is possible to be hit in the head by rocks or debris).

Plastic skull

Technological advances reach the masses in the form of flatter televisions, more capable telephones and faster computers, but medicine is the other great protagonist of this growing human knowledge. Prostheses date back many centuries ; in fact, several millennia old, as indicated by the first known orthopedic arm, which was found in an Egyptian mummy from 2000 BC

Currently, the list of bones and members of the body that can be “recovered” through prostheses is very long: from the pelvis to the maxilla, through the knees and the nose. However, nothing is as impressive as the possibility of replacing the skull with a 3D printed plastic replica. It is a revolution that brings hope to those who depend on reconstructive surgery to continue living or to overcome terrible accidents.

Brain operation without cranial opening

Surgical interventions in the brain are, without a doubt, among the most risky and complex, since they require the opening of the skull. However, there is a procedure that avoids this need and that at the beginning of 2015 was practiced for the first time in Spain, after having been experimentally tested more than once in Switzerland and the United States.

For patients with Alzheimer’s, Parkinson’s, strokes, brain tumors and epilepsy, for example, the possibility of undergoing an operation without opening the skull represents a less violent and risky method of dealing with diseases that already cause them. enough suffering and upheavals.

The first patient to have undergone this process suffered from a progressive and complex neurological disorder known as essential tremor. The operation lasts approximately two and a half hours; Regarding the preparations, it is necessary to shave the patient’s head and put on a helmet whose function is to generate high-intensity ultrasound in the area to be treated, guided and focused by magnetic resonance.
