Muscular System Layers Comparison | Internal Body Organs Images

Biological diagram infographic titled "Muscular System Layers Comparison" centered on a clean labeled comparison diagram of two structures: left panel a biologically accurate cross-section of human skeletal muscle from superficial to deep, right panel a biologically accurate cross-section of smooth muscle wall layering for comparison, editorial-grade educational anatomy for university undergraduate level. Arrange 9 labeled parts around the central side-by-side diagrams with thin leader lines; each label must include a short heading in English and a one-line function description in English. Render an editorial scientific cross-section with tasteful anatomy, scientifically accurate proportions, clear separation of tissue layers, and sharp readable text. Include a small comparison legend showing striated vs non-striated organization. Labels to render exactly as follows: "Epimysium" — "Outer connective tissue sheath that surrounds the entire skeletal muscle."; "Perimysium" — "Connective tissue layer that bundles muscle fibers into fascicles."; "Endomysium" — "Delicate sheath that surrounds each individual muscle fiber."; "Fascicle" — "A bundle of muscle fibers organized for coordinated contraction."; "Skeletal Muscle Fiber" — "Long multinucleated cell specialized for voluntary force production."; "Myofibrils" — "Contractile rods containing repeating sarcomeres that generate tension."; "Sarcolemma" — "Excitable cell membrane that conducts signals across the muscle fiber."; "Smooth Muscle Layer" — "Sheet of spindle-shaped cells that contracts involuntarily in organ walls."; "Dense Connective Tissue" — "Supportive matrix that anchors and protects the muscle layers." Visual style: colorful kids-book with simplified but scientifically accurate forms, cool clinical blues palette with cyan, navy, teal, and soft ice-blue accents, friendly academic mood, clean white background, subtle flat shading, crisp vector outlines, balanced composition, medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. 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.
