[Vessel architecture of cortical arteries of the human cerebrum]

The typical vascular patterns of cortical and medullar arterial vessels of the human brain in the subarachnoidal space are described. In compact arrangements and by bundles they penetrate the cortex, always in vertical direction to the cortex surface. From the top of gyri the medullar arteries run rectilinear through the cortical and medullar tissue. Medullar arteries which entrance the slope of the gyri turn in the direction of the medullar fibres after penetration the grey matter. Often glomerular-loop formations of medullar arteries are found in senile brain in the zone of fibrae arcuatae longae et breves.
