Which tissue cushions joints and reduces friction between bones?

• A. Bone Marrow
• B. Cartilage
• C. Compact Bone
• D. Ligaments

Answer: (B)

Fridge the main idea is that smooth, cushioned surfaces in joints are essential for easy, pain-free movement. Cartilage provides that cushion by covering the ends of bones within a synovial joint, creating a smooth, low-friction surface for bones to glide over each other. This articular cartilage—often hyaline cartilage—helps distribute the load across the joint and absorb shocks, reducing wear as you move. In contrast, bone marrow is inside bones and handles blood cell production and fat storage; compact bone is the dense tissue that gives bones strength; ligaments connect bones to each other to stabilize joints, but they don’t cushion or reduce friction themselves. So cartilage is the tissue that best fits the role of cushioning joints and lowering friction between bones.
