Kapitel 2: Gelenk & Muskelarbeit Illustrationen

Create a clean flat-vector educational illustration in 2:3 portrait format. White background, no shadows, no gradients. Sans-serif font. All labels in German. Title at top (bold, large): "Kapitel 2 – Selbstüberprüfung | Gelenk, Bandscheibe & Muskelarbeit" --- SECTION 1: BEWEGUNGSAUSMASS (Frage 9) --- Subtitle: "9. Faktoren für das Bewegungsausmaß" Draw a simple joint silhouette in the center. Around it, place 4 labeled boxes connected with arrows pointing TO the joint: Box 1 (top-left, red): "1. Gelenkform" → "Passung Kopf/Pfanne" Box 2 (top-right, blue): "2. Muskulatur" → "Kraft + Dehnfähigkeit" Box 3 (bottom-left, green): "3. Gelenkkapsel" → "Weite + Eigenspannung" Box 4 (bottom-right, orange): "4. Bandapparat" → "hemmend + sichernd" --- SECTION 2: BANDSCHEIBENVORFALL (Frage 10) --- Subtitle: "10. Bandscheibenvorfall (Prolaps)" Draw 2 cross-sections of intervertebral discs side by side: LEFT (labeled "Normal"): - Two rectangular vertebrae (gray) with space between them - In the space: outer ring of concentric oval lines (label: "Anulus fibrosus") - Inner oval filled with light blue (label: "Nucleus pulposus – zentriert") - Small arrows from nucleus pointing equally outward in all directions RIGHT (labeled "Vorfall / Prolaps"): - Same vertebrae but anulus fibrosus has a BREAK/GAP on one side (red crack line) - Nucleus pulposus material bulging OUT through the gap (red blob) - Below/beside the bulge: a thin vertical line (label: "Spinalnerv") being compressed - Red exclamation callout: "→ Schmerzen, Taubheit, Lähmung möglich" --- SECTION 3: MUSKELARBEITSFORMEN (Frage 11) --- Subtitle: "11. Formen von Muskelarbeit" Draw 3 side-by-side arm diagrams (simplified stick-arm with bicep highlighted): LEFT ARM: "Isotonisch (konzentrisch)" - Arm bending upward, muscle shortening, dumbbell rising - Arrow: "Muskel verkürzt sich" | "Bsp.: Gewicht hochheben" CENTER ARM: "Isometrisch (statisch)" - Arm held at 90°, no movement, muscle tense - Arrow: "Keine Längenänderung" | "Bsp.: Gewicht halten" RIGHT ARM: "Exzentrisch (negativ-dynamisch)" - Arm lowering slowly, muscle lengthening under tension, dumbbell descending - Arrow: "Muskel verlängert sich bremsend" | "Bsp.: Gewicht absenken" Color the bicep: green=isotonisch, yellow=isometrisch, orange=exzentrisch.
