To unite bones and prevent undesirable movement

To absorb shock during movement

To produce synovial fluid for joint lubrication

Verified step by step guidance

Step 1: Understand the structure and function of synovial joints. Synovial joints are the most movable type of joint in the body, characterized by a joint cavity filled with synovial fluid, which reduces friction and allows smooth movement.

Step 2: Define ligaments. Ligaments are strong bands of dense connective tissue that connect bones to other bones at joints. They are primarily composed of collagen fibers, which provide strength and flexibility.

Step 3: Explore the role of ligaments in synovial joints. Ligaments stabilize the joint by holding the bones together and preventing excessive or undesirable movements that could lead to injury.

Step 4: Eliminate incorrect options. For example, ligaments do not provide nutrients to articular cartilage (this is the role of synovial fluid) or produce synovial fluid (this is done by the synovial membrane). Ligaments also do not primarily absorb shock; this is the role of structures like cartilage and menisci.

Step 5: Conclude that the primary function of ligaments at synovial joints is to unite bones and prevent undesirable movement, ensuring joint stability and proper function.
