Former and present aspects in neuro-skull architecture.

ABSTRACT

The classical authors considered the functional resistance of the neuro-skull to consist of arcs at the arch level, rafters at the base and pillars at the joint of the arcs and rafters, those last also connecting the neuro-skull framework and that of the viscero-skull. The new outlooks replace the term pillar with that of resistance node and assemble the arcs and rafters within common structures, named resistance belts. The belts are one in transversal, three sagittal, two in frontal plane and two oblique positions. At the intersection of the belts, the resistance nodes are placed.
