Poster Anatomi Neuron Ilmiah

Create a highly detailed scientific anatomical poster of a {argument name="subject" default="neuron"} on a clean warm off-white paper background, presented as a museum-quality hybrid of 3D pencil drawing and ultra-realistic biological illustration. The composition centers on one large neuron in three-quarter view, with an oversized spherical purple nucleus inside a textured cell body, many branching dendrites spreading outward like winter tree branches, and a long axon extending diagonally down to the right. The axon is partially cut away to reveal its internal structure and is wrapped in segmented blue-gray myelin sheaths with visible gaps at the nodes of Ranvier. At the far end, the axon branches into exactly 15 thin terminal fibers, each ending in a rounded synaptic bulb with pale peach and pink tips. The main central figure should look sculptural, organic, and slightly glossy, with intricate membrane textures, subtle beige, ivory, silver, brown, and violet coloration, and extremely fine linework for the distal branches. Surround the centerpiece with 6 labeled educational inset sections arranged like a textbook infographic: top left a title block reading {argument name="title text" default="NEURON (NERVE CELL)"} with a short explanatory paragraph and a numbered structure list containing exactly 10 items; upper right a smaller monochrome full-neuron sketch labeled {argument name="style note" default="3D PENCIL DRAWING"}; lower left a cell body soma detail diagram with labels pointing to internal organelles; bottom left a myelin sheath cross-section cylinder diagram; lower center a square grayscale microscopic view panel with 4 labels; right center an electrical signal section with a small action potential graph showing membrane potential versus time; lower right a synapse close-up drawing with receptor and neurotransmitter labeling. Include fine serif typography, delicate leader lines, small circled numbers on the main neuron, and the feel of an elegant old scientific plate mixed with modern biomedical visualization. Keep the layout airy and balanced, with the central neuron dominating most of the canvas, landscape orientation, extremely high resolution, crisp educational poster design, and a refined neutral aesthetic.
