ИСТИНА

Skull as a complicated mechanical construction, consists from 28 different bones, connected by sutures of different structural kinds - from smooth ( face cranium) to teeth-like hardness (brain cranium). Basically, skull can be selected as face skull and brain skull. The last is composed from 8 bones with complicated connections between them, and namely brain skull will be described in the chapter presented. Structure of “brain skull” (or simply – skull) is the most complicated, it is changeable and individual depending on age, sex and race. The most pronounced mechanical changes of skull properties are observed in babies and juniors which are connected with brain growing. structural changes of the skull are concerned with structure of bone sutures, which tissues loss their elasticity with age. Volume of internal cavity of the skull of adult persons is balanced closely with volume of intracranial media so precisely, that the relief of internal surface of skull bones reflect the structure of the brain and its vascular system. This confirms the idea, that skull plays protector function for brain, and it is well known.
