Which joint function is NOT associated with ligaments?

Ligaments are strong bands of connective tissue that connect bones to other bones at joints. Their primary functions include providing stability to joints by preventing excessive movement, allowing for a certain range of motion without compromising joint integrity, and protecting joints from injury during movement.

Given this context, the function that is not associated with ligaments is connecting muscle to muscle. This role is actually fulfilled by tendons, which connect muscles to bones and thus facilitate movement by transferring the force generated by muscles to the skeletal system. In contrast, ligaments do not serve to connect muscles to one another; instead, they focus on maintaining the integrity and stability of the joints themselves.

The functions of allowing joint movement, preventing excessive movement, and protecting joints are all directly attributable to the role of ligaments in the musculoskeletal system, highlighting their importance in joint function and overall biomechanics.
