Multiple Choice

What is a key difference between cartilage and bone in terms of their structure and function?

Cartilage cells are called osteoblasts, while bone cells are called chondrocytes.

Bone is primarily composed of collagen fibers, whereas cartilage is made of osteocytes.

Cartilage contains more calcium deposits than bone, making it harder.

Cartilage is more flexible and lacks blood vessels, while bone is rigid and highly vascularized.

Verified step by step guidance

Identify the main structural components of cartilage and bone. Cartilage is primarily composed of chondrocytes and a gel-like matrix, while bone is composed of osteocytes, collagen fibers, and a mineralized matrix.

Understand the vascularization differences. Cartilage is avascular, meaning it lacks blood vessels, which contributes to its flexibility and slower healing process. In contrast, bone is highly vascularized, allowing for nutrient delivery and waste removal, contributing to its rigidity and faster healing.

Consider the functional implications of these structural differences. The flexibility of cartilage allows it to cushion joints and absorb shock, while the rigidity of bone provides structural support and protection for the body.

Recognize the role of calcium deposits. Bone contains significant calcium deposits, contributing to its hardness and strength, whereas cartilage has fewer calcium deposits, making it more flexible.

Summarize the key difference: Cartilage is more flexible and lacks blood vessels, while bone is rigid and highly vascularized, which aligns with their respective functions in the body.
