Cartilage is composed of a dense extracellular matrix rich in collagen fibers and proteoglycans, with chondrocytes (cartilage cells) residing in lacunae scattered throughout. This structure provides flexibility and support while allowing for the smooth movement of joints. In contrast, bone has a highly organized matrix that includes collagen fibers and mineral deposits, primarily hydroxyapatite, which give it strength and rigidity. Bone cells, including osteocytes, osteoblasts, and osteoclasts, are embedded in the matrix and play crucial roles in bone maintenance and remodeling.

How is cartilage different from bone in terms of structure and function?
Cartilage is a flexible connective tissue that is softer and more elastic than bone. It provides support and cushioning between bones, while bone is a hard, rigid tissue that provides structure and support for the body. Cartilage does not contain blood vessels or nerves, while bone is a living tissue with blood vessels and nerves.
Is spngy bone filled with cartilage?
No, spongy bone is not filled with cartilage. Spongy bone is a type of bone tissue that consists of trabeculae which form a lattice-like structure filled with bone marrow. Cartilage is a different type of connective tissue that is found at the ends of bones, in the joints, and within the nose and ears.
