Are there blood vessels present in cartilage?

• A. Yes, many blood vessels
• B. No, cartilage is avascular
• C. Yes, but only in mature cartilage
• D. Only in fibrocartilage

Answer: (B)

Cartilage is classified as an avascular tissue, meaning it does not contain blood vessels. This lack of vascularity is one of the defining characteristics of cartilage and contributes to its unique healing properties; it has a limited ability to repair itself due to the absence of blood supply. Instead of receiving nutrients through blood vessels, cartilage relies on diffusion from surrounding tissues to obtain necessary nutrients and remove waste products. In different types of cartilage—such as hyaline, elastic, and fibrocartilage—the avascular nature is consistent, although fibrocartilage does have a higher degree of collagen and may contain a few blood vessels in its periphery due to its relationship with surrounding tissues. However, within the cartilage matrix itself, the general rule holds that blood vessels are not present. Thus, recognizing cartilage as avascular is crucial for understanding its biological behavior and responses to injury or disease.
