The Secrets of Joints
★Exhibit Content: Structures of various human joints, movement forms, and joint protection knowledge ★Interaction: Mechanical manual interaction ★Operation: Observe the human skeletal joint model to understand the basic joint structure; manually operate the simulated joint models to experience the movement modes of different joints. ★Exhibit Description: The Secret of Joints is a science popularization exhibit under the human body science theme and a recommended exhibit of the PopsciCat Exhibit Store. The exhibit consists of a curved display stand, a background modeling board, a transparent protective cover, and multiple sets of human joint simulation models. On the display stand, there are 6 sets of manually operable simulated joint models, including pivot joints, ball-and-socket joints, saddle joints, ellipsoid joints, plane joints, etc., along with physical specimen models such as knee joints, foot joints, and hand joints. Visitors can manually move each joint model to perform flexion, extension, adduction, abduction, rotation, and circumduction, intuitively observe the range of motion of different joints, and, combined with the graphic and textual labels on the tabletop, learn about the distribution and functions of various joints in the human body as well as science knowledge related to daily joint protection and maintenance. ★Scientific Principle: The connection between bones is called a bone connection, and joints are an important type of indirect bone connection. The bone structures of different joint forms determine their respective degrees of freedom of movement. Ball-and-socket joints can achieve multi-directional and large-range movement, pivot joints only allow rotational movement, and plane joints can only slide slightly. This exhibit replicates various joint structures through physical simulation models, allowing visitors to operate them by hand and intuitively understand the correspondence between joint structure and movement capability, thereby establishing a basic understanding of the human musculoskeletal system.
