What is the specialized cartilage that covers the surfaces of bones in synovial joints called?

The specialized cartilage that covers the surfaces of bones in synovial joints is known as articular cartilage. This type of cartilage plays a crucial role in the function and health of synovial joints, providing a smooth, lubricated surface that facilitates the movement of bones within the joint. Articular cartilage is essential for reducing friction between the bone surfaces during movement and helps to absorb shock, ensuring that the bones do not rub against each other directly, which could lead to wear and tear or injury.

Articular cartilage is a form of hyaline cartilage, characterized by its glassy appearance and smooth texture. While hyaline cartilage can refer to other structures in the body, the term "articular cartilage" specifically denotes the hyaline cartilage that caps the ends of bones in synovial joints. This distinction is important in understanding joint anatomy and function, particularly when discussing joint pathologies or injuries.
