What is the primary function of ligaments in the body?

The primary function of ligaments is to connect bone to bone. This connective tissue plays a vital role in reinforcing joints by holding bones together, thereby contributing to the stability and integrity of the skeletal structure. Ligaments are composed of dense connective tissue, which allows them to withstand the stress and strain of movement while preventing excessive motion that could lead to joint injuries.

While ligaments do help provide stability to joints, which is an important aspect of their function, the fundamental role they play is specifically the connection between bones. This is distinct from tendons, which attach muscles to bones and are important for movement. Understanding that ligaments serve the essential purpose of connecting bones helps clarify their indispensable role in the musculoskeletal system.
