Arguments justifying the acception of the notion "sublobular artery" in the nomenclature of renal vessels: the "conical" architectonics of the renal cortex.
The corrosion technique was used to demonstrate the presence of the "sublobular artery", a constant vessel with a special profile of the dog kidney, generating after two divisions the so-called interlobular arteries as a third generation of branches. More rarely arteriae interlobulares emerge also directly from the arcuate artery. The sublobular arteries (= parent vessels of the interlobular arteries) are characterized by their particular origin, branching type, and by having no or sporadically disposed glomeruli. For this reason, the authors suggest the acception of the term "arteria sublobularis" in the international nomenclature of renal vessels. According to authors' opinion the dog kidney is composed of a number of conical vascular-parenchymatous units, each containing in their axis a sublobular artery of the second order ("conical" architectonics of the renal cortex).
