What is the major role of ligaments at synovial joints?

• A. To produce synovial fluid for lubrication
• B. To initiate muscle contraction
• C. To connect bones and stabilize the joint
• D. To cushion the joint and absorb shock

Answer: (C)

Verified step by step guidance

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.
2. Identify the role of ligaments: Ligaments are tough, fibrous connective tissues that connect bones to other bones at joints. Their primary function is to provide stability and prevent excessive movement that could lead to injury.
3. Eliminate incorrect options: Review the provided choices and eliminate those that do not align with the function of ligaments. For example, ligaments do not produce synovial fluid, initiate muscle contraction, or cushion the joint.
4. Focus on the correct function: Ligaments stabilize synovial joints by limiting their range of motion and ensuring the bones remain properly aligned during movement.
5. Conclude with the correct answer: Based on the analysis, the major role of ligaments at synovial joints is to connect bones and stabilize the joint.
