Scientific Neuron Anatomy Poster

Create a highly detailed scientific anatomy poster, with the main subject being {argument name="subject" default="neurons"} The background is a clean, warm off-white paper, presenting a hybrid style of museum-quality 3D pencil sketches and hyper-realistic biological illustrations. At the center of the composition is a large neuron viewed in three-quarters of its length, containing a huge, spherical, purple nucleus. Numerous branching dendrites extend outwards like winter branches, and a long axon extends obliquely to the lower right. The axon is partially cut open to reveal its internal structure, encased in segmented blue-gray myelin sheaths with distinct gaps at the nodes of Langefier. At the terminal end, the axon branches into 15 slender terminal fibers, each ending in a rounded synaptic ball with pale peach and pink tips. The central element should appear sculptural, organic, and slightly glossy, with complex membrane textures in subtle shades of beige, ivory, silver, brown, and purple, with extremely fine lines on the distal branches. Surrounding the central element are six labeled educational illustration panels, arranged like a textbook infographic: the top left panel is the title panel with text {argument name="title text" default="Neuron (nerve cell)"} It includes a brief explanatory text and a numbered list of 10 items; the upper right corner features a smaller monochrome sketch of the entire neuron, labeled as {argument name="style note" default="3D pencil sketch"} The bottom left corner features a detailed image of the cell body, labeled to point to internal organelles; the bottom left shows a cylindrical cross-section of the myelin sheath; the bottom center features a square grayscale microscope view panel with four labels; the right center shows an electrical signal section with a small action potential graph displaying membrane potential changes over time; the bottom right corner shows a close-up of a synapse, labeled with receptors and neurotransmitters. The use of fine serif fonts, delicate guide lines, and small circular numbers on the main neurons creates a feel that blends elegant, old-fashioned scientific illustrations with modern biomedical visualization. Maintaining a transparent and balanced layout, the central neuron occupies most of the canvas, with a horizontal composition, extremely high resolution, clear educational poster design, and a refined neutral aesthetic.
