What is the primary function of ligaments?

Ligaments are specialized connective tissues that play a crucial role in the musculoskeletal system by connecting bones to other bones. This function is vital for maintaining joint stability and providing support during movement. Ligaments help to reinforce joints and can restrict excessive movement, which is essential for maintaining proper function and preventing injuries. They also contribute to the overall structural integrity of the skeletal system.

The other options describe functions that are characteristic of other tissues; for example, tendons are the structures that connect muscles to bones, playing an integral role in facilitating movement by transmitting the force generated by muscles. While ligaments do assist in the support of structures within the body, their primary role is specifically to connect bone to bone, which is what makes the correct choice stand out.
