EPIPHYSIS, EPIPHYSIAL LINE purple The opiphysis is the end of a long bone. Extemally it has a thin layer of compact bone, while internaly the bone is cancellous. The Epiphysis is capped with articular cartilage. DIAPHYSIS (shaft)- label The diaphysis is the shaft of the long bone. It has compact bone with a central cavity ARTICULAR CARTILAGE-green The articular cartilage found on the ends oflog bones. smooth, sippery, and bloodless is PERIOSTEUM-dark blue Periosteum is a fibrous, vascular, sensitive Ife support covering for bone. It provides nutrient-rich blood for bone cells and is a source of bone-developing cels during growth or after a fracture SPONGY BONE, RED MARROW-ight blue The canoelious bone appears as tiny beams of bone arranged like a lattice. Red marrow packs the spaces between beams. 8 COMPACT BONE-pink The compact bone is a dense bone found in the diaphysis. Its repeated patdern is arranged in concentric layers of solid bone tissue. MEDULLARY CAVITY, YELLOW MARROW -yellow The medular cavity of the diaphysis serves to lighten bone weight and provide space for its marrow.
