Models and mannequins are life-like replicas used for various purposes, including education, training, and display. In the medical field, they are often used for simulation-based learning, allowing students and professionals to practice procedures like CPR, surgery, or injections. In fashion and retail, mannequins display clothing and accessories, helping customers visualize how garments fit and look. These models are designed to replicate the human form accurately, whether for functional or aesthetic purposes. Advances in technology have led to more realistic and interactive models, enhancing their effectiveness in both medical and commercial settings.
