What is the primary function of ligaments in the body?

The primary function of ligaments in the body is to attach bone to bone. This connection is crucial for maintaining the stability of joints, helping to prevent excessive movement that could lead to injuries. Ligaments are made of dense connective tissue that is flexible yet strong, allowing them to support joints while still permitting a certain range of motion. This helps to ensure that the skeletal structure remains intact and functional during physical activities.

Other choices focus on different structures and functions within the musculoskeletal system. For instance, the attachment of muscle to bone is the role of tendons, while cushioning between bones is typically provided by cartilage. Facilitating joint movement is more closely associated with the roles of muscles and synovial fluid rather than ligaments. Thus, ligaments specifically serve the vital role of connecting bones at joints, highlighting their importance in maintaining overall joint integrity and function.
