Detailed Illustration of Healthy Human Nerve Cell

Generate a highly detailed and scientifically accurate illustration of a healthy human nerve cell, highlighting the central component - the nerve fiber with an intact myelin sheath. Ensure that the illustration portrays the structure of the nerve cell accurately, including the axon, dendrites, and cell body. Pay special attention to the myelin sheath's depiction, emphasizing its insulating properties and the nodes of Ranvier. The final image should reflect the intricate and delicate nature of this essential cellular structure, adhering to current scientific knowledge and visual standards for accuracy.
