Autonomic nervous system

Simplified schematic of the human autonomic nervous system in clean educational clipart style, showing a central spinal cord within a pale beige torso silhouette and paired nerve trunks running vertically alongside the spine. Bilateral sympathetic chains appear as bead-like ganglia on both sides of the spinal cord, with thin yellow to yellow-gold branching nerve fibers extending outward to internal organs. Include a few cranial and sacral parasympathetic outflows and more diffuse parasympathetic branches, using muted tan, cream, and light yellow tones for the nerves and ganglia. The layout is symmetrical and stylized, representing visceral autonomic pathways.
