Which structure connects bone to bone?

The structure that connects bone to bone is a ligament. Ligaments are made of dense connective tissue and play a critical role in maintaining the stability of joints by connecting adjacent bones together. They help to control the range of motion at the joint and prevent excessive movement that could lead to injury.

Tendons, on the other hand, connect muscles to bones, allowing for movement when the muscle contracts. Cartilage provides cushioning between bones in a joint and is instrumental in facilitating smooth movement but does not connect bones to one another. Muscles are responsible for generating movement, but they do not directly connect bones to each other in the way ligaments do. Understanding the distinct roles each of these structures plays is crucial for grasping the complexities of musculoskeletal anatomy.
