Arteries ligaments. Arteries of the brain.
The content of the body includes its vascular system, which is part of the body as a whole. Therefore, the nature of the intraorgan arterial bed and the architectonics of the intraorgan arteries correspond to the structure, function, and development of the organ in which these vessels branch out (M. G. Prives). This explains that in different organs the arterial bed is constructed differently, and in similar organs it is approximately the same.
Brain arteries also go from the periphery to the center, and:
a) in the cerebral cortex (screen centers) they have the form of straight and short arteries,
b) in the white matter – direct and long, running along the nerve bundles, and c) vascular networks form in the subcortical nuclei (nuclear centers). In the nerve roots and nerves, the arteries run in endoneurium layers in parallel to the bundles of nerve fibers, to which, like in muscles, they are delivered perpendicular branches, forming longitudinal loops extending along the nerve bundles.
Thus, in organs built from a system of fibers (muscles, ligaments, nerves), the arteries are about the same: they enter in several places along the length of the organ and are located along the fibers. For the nutrition of this organ, not only the arteries that enter directly into it, but also the neighboring ones that give blood through the anastomosis are important. All the arteries of a given organ and its surrounding formations constitute the “organ system of vessels”.
