[Morphologic characteristics of the vascular network in the gyrus rectus in humans].
The objective of this research was to assess morphological features of gyrus rectus frontal cortex vascular network, regarding its laminar and columnar organization. In all researches adult brains were used. Blood vessels were injected by mixture of india ink and gelatine. After the fixation and embedding in paraffin, parts of cortex have been cut in series, tangentionally and perpendicularely in respect to the surface. Strictly defined vascular layers of gyrus rectus vascular network were not found. All types of arteries were present in the vascular network but A3 and A4 arteries were dominant. In the gyrus rectus the fountain-like arteries were found with some branches divided in fountain-like branches, too. Boreder zones of lower vascular density were found between capillary network of the two adjacent cortical arteries. All types of veins were found in the cortex but they were smaller in calibre. Vertically oriented vascular units were also found in gyrus rectus.
