What is the primary function of articular cartilage?

• A. Provides strength to the bone
• B. Protects the bone ends and facilitates smooth movement of joints
• C. Connects bones at joints
• D. Contains yellow bone marrow

Answer: (B)

Articular cartilage plays a crucial role in joint function and health. Its primary function is to protect the ends of bones at the joint surfaces, providing a smooth and lubricated surface that allows for frictionless movement during joint motion. This protective layer helps to absorb shock and distribute loads during activities such as walking, running, and jumping, thereby reducing wear and tear on the underlying bone structures. While articular cartilage does contribute to overall joint stability, it does not provide strength to the bone, connect bones at joints, nor does it contain yellow bone marrow, which is primarily found in the medullary cavities of long bones. The absence of a direct connection to the bone ends or strength transmission distinguishes its specific role in promoting smooth joint function and protecting the bony surfaces from damage during movement.
