Deep anatomy layers (bones, muscles, tendons, vessels, nerves) rendered from Z-Anatomy (models derived from BodyParts3D, © The Database Center for Life Science), licensed CC BY-SA 4.0 — those images share that license. Skin-layer figures are AI-generated (SDXL, locally on a DGX Spark) and depict no real person; deep layers show the shared male atlas for every patient. Body-build variants stretch the figures. Dermatome regions are schematic; acupoint positions are approximate. Not a medical device; clinical judgment required.
