Which component of a synovial joint is responsible for reducing friction during movement?
Ligaments
Articular cartilage
Joint capsule
Synovial fluid
The Correct Answer is D
A. Ligaments: Ligaments stabilize and limit joint movement but do not primarily reduce friction.
B. Articular cartilage: Articular cartilage provides a smooth, low-friction surface and shock absorption, helping reduce friction.
C. Joint capsule: The joint capsule encloses and stabilizes the joint and contains synovial fluid but is not the main friction-reducing element.
D. Synovial fluid: Synovial fluid lubricates the joint surfaces, nourishes cartilage, and significantly reduces friction during movement.

Correct Answer is C
Explanation
A. To produce synovial fluid:Synovial fluid is produced by the synovial membrane (lining of the joint capsule), not by the articular cartilage.
B. To connect bones:Structural connections between bones are provided by ligaments rather than articular cartilage.
C. To absorb shock and reduce friction:Articular cartilage provides a smooth, resilient surface that distributes load and reduces friction between joint surfaces during movement.
D. To facilitate nerve signaling:Articular cartilage is avascular and largely aneural, so it does not play a direct role in nerve signaling.
Correct Answer is B
Explanation
A. Absorbing shock:Shock absorption is mainly performed by articular cartilage and synovial fluid rather than ligaments.
B. Providing joint stability:Ligaments are strong fibrous bands that connect bones to bones, maintaining alignment and stability during movement.
C. Connecting muscles to bones:This function is carried out by tendons, not ligaments.
D. Lubricating the joint:Lubrication is provided by synovial fluid within the joint capsule, not by ligaments.
