A manikin, also known as a dummy, is a life-sized model of the human body used for various purposes, including education, training, and display. Manikins are commonly used in fields such as medicine, fashion, and art. In medical training, they help students practice procedures like CPR or surgical techniques without risking harm to real patients. In the fashion industry, manikins serve as display figures for clothing and accessories, allowing designers to showcase their work. They come in various forms, including articulated models for movement and static models for visual presentation. Manikins can be made from materials like plastic, fiberglass, or foam.
