nervous system 3d model

Ultra-detailed 3D medical visualization of the human nervous system ONLY. No skin, no muscles, no bones, no other organs visible. Full body outline with complete nervous system shown, including brain, spinal cord, cranial nerves, and peripheral nerves. Anatomically accurate and scientifically precise. Animation demonstrating both motor and sensory nerve pathways. A human hand opens and closes slowly. Motor nerve signals originate in the motor cortex of the brain, travel down the spinal cord, branch into peripheral nerves, and reach the hand. The nerve signals are visualized as glowing electrical impulses moving in real time. The hand is then touched or pressed, triggering sensory nerve signals that travel from the fingers through sensory nerves, up the spinal cord, and into the brain. Sensory signals are clearly distinguished from motor signals using different glow intensity or color. Relevant brain regions are highlighted during activity: motor cortex during movement, somatosensory cortex during touch per
