What is the primary function of ligaments in the body?

The primary function of ligaments is to stabilize the joints. Ligaments are tough, fibrous connective tissues that connect bones to other bones at a joint, providing both stability and support. They help maintain proper alignment and prevent excessive movements that could lead to injuries or joint instability. By securing the bones in place, ligaments ensure that joint function remains optimal during activities, allowing for a range of motion while protecting against dislocations and other joint-related injuries.

In contrast, the other options describe functions that are attributed to different structures in the body. For example, moving a joint is primarily the role of muscles, which contract to create movement at the joints. Connecting muscles to bones is the function of tendons, not ligaments, while ligaments do not connect muscles to each other but rather play a pivotal role in joint stabilization.
