Bone: the organ - articular cartilage
The ends of long bones are covered by articular cartilage, formed of hyaline cartilage, providing a smooth, glassy surface that allows the ends of the bones to move easily on each other. This type of articulation is called a synovial joint. Articular cartilages, which are not covered by periosteum, are separated by a fluid-filled synovial space. A thin layer of compact bone lies beneath the cartilage. 10x, 800x

This higher magnification of the area indicated by the green rectangle shows the interface of the compact bone of the epiphysis with articular cartilage. Osteocytes in lacuna are evident in the compact bone.
