What is the role of ligaments in joint stability?

Ligaments play a crucial role in joint stability by attaching bone to bone. This connection provides structural support and helps maintain the integrity of the joint during movement. Ligaments are composed of dense connective tissue and have a limited capacity to stretch, which allows them to restrict excessive or abnormal movement. This restriction is vital for preventing injuries, such as dislocations and sprains, by ensuring that the bones remain in the correct position relative to each other during various activities.

The other roles mentioned in the choices are filled by different structures within the musculoskeletal system. For instance, muscles connect to bones via tendons, and cushioning of the joint is typically provided by cartilage. While ligaments can contribute indirectly to joint movement by stabilizing the joint, their primary function is to provide stability through the connection between bones.
