What role do ligaments play in the skeletal system?

Ligaments play a crucial role in the skeletal system by connecting one bone to another. This connective tissue is composed of dense, fibrous material that provides stability to joints and helps to maintain the structural integrity of the skeletal framework. By connecting bones, ligaments limit the range of motion to protect against excessive movement that could lead to injuries, dislocations, or other joint-related problems. They are essential for maintaining proper alignment and function of joints during activities involving movement and weight-bearing.

The other options refer to different structures within the musculoskeletal system. For example, connecting muscle to bone is the function of tendons, while the protection of vital organs is typically provided by the rib cage and other bony structures in the body. Locomotion involves the coordinated action of muscles, bones, and joints, but it is not the primary function of ligaments themselves. Thus, the primary role of ligaments is indeed to connect bones to one another, providing stability to the skeletal system.
