Which connective tissue structure acts as a shock absorber in synovial joints?

• A. Retinaculum
• B. Fat pad
• C. Articular cartilage
• D. Joint capsule

Answer: (C)

Articular cartilage plays a crucial role in synovial joints by acting as a shock absorber. This specialized type of hyaline cartilage covers the ends of bones where they meet to form a joint. Its smooth, slippery surface reduces friction during movement, allowing for the bones to glide over each other seamlessly. Additionally, the unique structure of articular cartilage provides the ability to withstand compressive forces and helps to distribute loads more evenly across the joint, which is essential during activities such as walking, running, or jumping. By cushioning the impact of sudden forces, articular cartilage protects the underlying bone and contributes to the overall stability and health of the joint. In contrast, while structures like retinacula, fat pads, and joint capsules serve important functions, they do not specifically absorb shock in the same manner as articular cartilage does. Retinacula primarily stabilize tendons, fat pads provide cushioning and fill in spaces around joints, and joint capsules enclose and protect the joint, but none have the same direct impact-absorbing qualities as articular cartilage.
