👉 An articulator is a mechanical device that connects two or more different parts of an object, such as a joint or a bone, to form a complete joint. It allows for movement between the joints and enables the transfer of energy from one part to another. Examples of articulators include bones (e.g., shoulder, elbow), muscles (e.g., arm), ligaments (e.g., knee and hip), and tendons (e.g., hand).
