Which structure connects two bones together?

The structure that connects two bones together is ligaments. Ligaments are made of dense connective tissue and serve the crucial function of stabilizing joints by joining bones at various points in the body. They provide support while allowing for a certain degree of flexibility, essential for the range of motion required during movement.

Other options in this context serve different roles. Tendons connect muscles to bones, enabling the force generated by muscles to move the skeleton. Cartilage, while providing cushioning and support within joints, does not directly connect bones; instead, it often lines the surfaces where bones meet. Muscles, on the other hand, are responsible for movement but do not connect bones to one another. Therefore, the role of ligaments is distinct and vital for maintaining joint integrity and functionality.
