How do ligaments stabilize a synovial joint during movement?

How do ligaments stabilize a synovial joint during movement?

• A. They limit motion by attaching bones and guiding joint movement; they provide passive stability and contain mechanoreceptors for proprioception.
• B. They contract to move joints.
• C. They are the primary source of blood supply to bone.
• D. They produce synovial fluid.

Answer: (A)

Ligaments stabilize a synovial joint during movement by providing passive stability and guiding joint motion. They connect bone to bone and become taut as the joint moves, which limits excessive motion and helps steer the joint along its normal path. Many ligaments also contain mechanoreceptors that detect stretch and position, giving the nervous system proprioceptive feedback to fine-tune movement and prevent injury. Ligaments don’t contract to move joints—that’s the role of muscles—and they aren’t the primary source of blood supply to bone or producers of synovial fluid (that comes from the synovial membrane).
