Wissenschaftliches Neuron-Anatomie-Poster

A highly detailed scientific anatomical poster of a [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, branching dendrites spreading outward like bare tree branches, and a long axon extending diagonally down to the right. The axon is partially cut away to reveal its internal structure, wrapped in segmented blue-gray myelin sheaths with visible gaps at the nodes of Ranvier, terminating in exactly 15 thin fibers with pale peach and pink rounded synaptic bulbs. The central cell has a sculptural, organic, slightly glossy surface with subtle beige, ivory, silver, brown, and violet tones. Surrounding the centerpiece are 6 labeled educational inset sections: top left title block reading "[NEURON (NERVE CELL)]" with an explanatory paragraph and a 10-item numbered structure list; upper right monochrome sketch labeled "[3D PENCIL DRAWING]"; lower left cell body soma diagram with organelle callouts; bottom left myelin sheath cross-section cylinder; lower center grayscale microscopic view panel with 4 labels; right center action potential graph showing membrane potential versus time; lower right synapse diagram with neurotransmitter labels. Fine serif typography, delicate leader lines, numbered callouts, airy balanced textbook layout, landscape orientation.
