Sympathetic nervous system

Clean clipart-style anatomical schematic of the sympathetic nervous system with a central vertical spinal cord or vertebral column flanked by paired sympathetic chains on both sides. Each sympathetic chain is a pale yellow to yellow-gold longitudinal nerve trunk composed of thin vertical cords with segmented bead-like or oval ganglia shown as small slightly darker gold swellings. Fine branching sympathetic and peripheral nerve fibers extend outward from the chains, including some branches directed toward structures such as the heart and blood vessels, and small cross-connections between the paired vertical cords may be visible. Plain background, simplified educational medical diagram style, neatly organized and isolated.
