What is the role of a ligament?

A ligament plays a crucial role in the musculoskeletal system by connecting bone to bone. This structural tissue helps to maintain joint stability and integrity, ensuring that bones remain properly aligned during movement. Ligaments are composed of dense connective tissue, which allows them to withstand tension and provide support to joints, preventing excessive movement that could lead to injuries.

In contrast, the other options describe functions performed by different structures in the body. For instance, tendons connect muscles to bones, while muscle fibers are supported by connective tissues but do not serve the function of connecting bones directly. The specific role of ligaments in connecting bones reinforces their importance in overall joint health and mobility. Understanding this distinction is essential for anyone involved in rehabilitation or anatomical studies.
