Guida verificata passo dopo passo1
Understand the role of the extracellular matrix (ECM) in both bone and cartilage. The ECM provides structural and biochemical support to the surrounding cells.
Recognize that the ECM of cartilage is primarily composed of collagen fibers and proteoglycans, which provide flexibility and resilience. This allows cartilage to withstand compression and provide cushioning in joints.
Identify that the ECM of bone is composed of collagen fibers and mineral deposits, primarily calcium phosphate, which make it rigid and strong. This rigidity supports the body's structure and protects vital organs.
Compare the flexibility of cartilage with the rigidity of bone. Cartilage's ECM allows it to be more flexible, while bone's ECM is designed to be rigid and supportive.
Conclude that the ECM of cartilage is flexible, while the ECM of bone is rigid, which aligns with the correct answer: 'ECM of cartilage is flexible: ECM of bone is rigid.'
