Key benefits Makes learning human joints visual and interactive: bright, computer-matched colors distinguish joint parts and draw attention, improving student focus and comprehension during lessons or study. Hands-on, detachable design bridges theory and practice: 23 removable parts let learners assemble, disassemble, and rehearse basic procedures to reinforce understanding and practical skills. Safe, durable, portable model: made from food-grade, eco-friendly plastic with high-quality hand-painted finishing; lightweight (0.3 kg) and supplied with a display stand for easy storage and transport. What it is and how it helps 4D articulated human joint model that represents joint anatomy with high fidelity. The nearly true representation of bone, cartilage and connective positions helps learners visualize spatial relationships that textbooks and flat images cannot convey. Detachable components allow guided demonstrations, step-by-step lessons, and hands-on practice that increase retention and lesson quality. Puzzle-style interaction trains manual dexterity and problem-solving for pupils and children, making the model useful for both classroom instruction and supervised skill-building activities. Key features 4D anatomical joint model designed for teaching and practice 23 removable parts for assembly/disassembly exercises Includes display stand for stable presentation and storage Material: food-grade, eco-friendly plastic; computer color matching; hand-painted details Weight: approximately 0.3 kg — easy to carry between classroom, lab, or home Practical use scenarios Classroom demonstration: Use the model during lectures to show joint movement, explain components, and run step-by-step disassembly to illustrate how parts relate in three dimensions. Basic surgical skills or lab practice: Instructors can use removable parts to guide students through simulated procedures, helping combine theoretical knowledge with hands-on technique under supervision. Home learning and early education: Parents and tutors can use the puzzle-like model to build spatial reasoning and fine motor skills in children while reinforcing anatomy lessons in a low-pressure setting.
