What is the function of hyaline cartilage in a synovial joint?

• A. Provide blood supply
• B. Attach muscles to bones
• C. Decrease friction and provide sliding surface
• D. Produce nerve endings

Answer: (C)

Hyaline cartilage in a synovial joint provides a smooth, low-friction surface for the ends of bones to move against each other. It covers articular surfaces and, together with the synovial fluid, minimizes wear, cushions loads, and allows the bones to glide smoothly during movement. It’s avascular and aneural, so it does not supply blood or nerves, and the attachment of muscles to bones is done by tendons and ligaments, not cartilage. Damage to this cartilage increases friction and leads to joint wear and pain.
