Layers of the Muscular System Anatomy Infographic

Biological diagram infographic titled "Layers of the Muscular System" centered on a clean labeled diagram of the human body showing an editorial-grade anatomical cutaway and layer-by-layer branching structure inspired by an evolutionary tree layout, adapted to explain body tissue hierarchy simply for kids ages 8-12. Main figure in upright frontal view with simplified tasteful human anatomy, showing outer body outline and internal muscular layers with clear depth separation. Use a modern textbook visual style, vibrant educational primary palette, friendly and accessible mood, medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. Arrange 5 labeled callouts around the central diagram with thin leader lines; because the requested archetype is an evolutionary tree, organize the labels as branching tiers from outer layer to deeper muscle-related structures while keeping anatomy scientifically accurate. Include these exact English labels and captions: "Skin" — "Protects the body and covers the tissues below."; "Superficial Fascia" — "Stores fat and helps connect skin to deeper structures."; "Deep Fascia" — "Wraps and supports muscles, blood vessels, and nerves."; "Skeletal Muscle" — "Contracts to move the body and maintain posture."; "Tendon" — "Connects muscle to bone and transfers pulling force." Show each label with a short heading and one-line function description in sharp readable English text. Add a small simple legend indicating outer to inner organization. Keep proportions biologically accurate but age-appropriate, clean, and non-gory. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no graphic gore, no real patient photos, no watermarks No graphic medical gore, no real patient photographs, no surgical blood. For human anatomy, keep illustrations educationally tasteful. For animal anatomy, no cruelty imagery. Scientifically accurate labeling and proportions.
