What type of cartilage provides protection during movement at the ends of bones?

The correct choice is articular cartilage, which is specifically designed to cover the ends of bones in synovial joints. This type of cartilage is a type of hyaline cartilage, but it has distinct characteristics that facilitate its role in joint function. Articular cartilage has a smooth, slick surface that reduces friction between the articulating surfaces of bones during movement. This quality helps to prevent wear and tear, allowing for smoother motion and minimizing the risk of injury or pain during physical activity.

Articular cartilage also contributes to shock absorption, helping to distribute loads and stresses that occur during movements such as walking, running, and jumping. Its unique composition, which includes a high water content and specialized cells called chondrocytes, enables it to withstand compression and bending forces effectively.

While hyaline cartilage is a broader category that includes articular cartilage, the term "articular cartilage" is more precise in this context, highlighting its specific function in joint movement and protection. Elastic cartilage and fibrocartilage serve different functions; for instance, elastic cartilage provides flexibility (like in the ear), while fibrocartilage offers support and can absorb shock (like in intervertebral discs). Understanding these distinctions clarifies why articular cartilage is the most appropriate choice for this question.
