[Topographo-anatomic interrelationships between the branches of the lumbar arteries and the spinal ganglia, nerves and roots].
By using a complex of investigation methods variants of branchingout of the spinal cord and spinal ganglia blood supply sources and their anatomo-topographic interrelations were discerned in 140 preparations of lumbar spinal ganglia obtained from human cadavers of both sexes and different age. With the help of anastomoses these sources form a specific arterial circle around the ganglion. The radicular arteries are noted to be non-equivalent. The annular architectonics of the blood vessels is considered as a morphological manifestation of a functionally reliable blood supply to the border area between the central and peripheral divisions of the nervous system.
