Transcript of Structure and Classification of Bone/ Organization of the Skeleton.
• Cartilage and bone support the rest of the body
• Cartilage– Matrix is a firm gel– Cells called chondrocytes– Cells found in lacunae– Three types: hyaline, elastic and fibrocartilage
Supporting connective tissues
• Compact bone (dense)– Dense and forms the surface of bones – Extremely hard
• Spongy bone (cancellous)– low density and strength– fills the inner cavity of long bones – contains red bone marrow where the
production of blood cellular components (known as hematopoiesis) takes place
Bone structure = two types of bone
