The skull - the protective shell of the brain

Those who are called "thick skulls" are seldom happy about this designation. It is not that bad to have a thick and therefore as shockproof skull as possible. On average, women even have a slightly thicker skull than men. Find out here what makes the hollow and round bone structure so unique.

The skull is made of bone substance like a capsule and sits on the trunk, connected by the cervical spine. It forms a protective cover around the brain. At the front of the skull is the head or face. The skull has several openings, of which the mouth, the area of ​​the eye sockets, the transition of the nose and the inwardly opened auditory canals of the ears are evident. The skull is also unlocked in the neck area. The important supply lines and nerves run through this channel. The muscles, fasciae and tissue as well as skin and hair are located on the skull.

As a bone structure, the skull is part of the skeleton. It can be roughly divided into two areas: The brain skull, the stable covering around the brain, consists of seven firmly connected individual bone plates that are on average around 6 millimeters thick. The skull shows up to the front. Its characteristic shape with its many bulges and edges is the basis of the human face. It consists of about 15 individual small bones, some of which include the hyoid bone and the bones of the ear canal. The temporomandibular joint is connected to the skull at the bottom.

The most important task of the skull is to protect the brain. Since the brain is central to survival, the skull securely embeds the soft brain matter inside. For this reason, the skull roof is particularly stable and thick. It is probably no coincidence that the other important sensory organs (mouth, eyes, nose, ears) are also all located in the skull: it offers the greatest possible protection. It shows that the bony construction is cleverly built. In order to save weight and not to make the skull proportionally unnecessarily heavy, the front areas of the facial skull are predominantly constructed in the form of light but stable sinuses.

Injuries and diseases of the skull

The skull is extremely robust and can take many shocks without any problems. Nevertheless, massive violence, such as an accident or impact, can lead to a fracture of the skull bones. Practically all individual bones of the skull can be broken or shattered, as in the case of a skull base fracture or a skull fracture. A rupture is particularly bad if tissue water is drained from the brain or if there is bleeding under the top of the skull. Injured bony areas, on the other hand, usually heal very quickly. In rare cases, carcinomas from the brain or meninges can also affect and attack the edge of the skull.
