This interactive 3D model visualizes the human nervous system, presenting major anatomical structures like the brain, spinal cord, and peripheral nerves. Using Three.js with its OrbitControls and CSS2DRenderer, it renders anatomically detailed components including gray matter, dorsal root ganglia, and the cauda equina. Users can select different system views—Central Nervous System, Peripheral Nervous System, Neuron Structure, or Spinal Cord—through a dropdown menu, with clickable structures displaying functional descriptions. The visualization employs distinct color-coded regions for each anatomical part, with a detailed spinal cord view that includes vertebral structures, meningeal layers, and cross-sectional perspectives.
