Cartilage heals poorly following an injury because 

Options

A. It has no blood supply
B. It has no cells
C. It has no fibres
D. It has no nerves

Answer

**Step-by-Step Solution:**

1. **Understanding Cartilage**: Cartilage is a type of specialized connective tissue that plays a crucial role in the body, providing support and flexibility to various structures.

2. **Blood Supply**: One of the key characteristics of cartilage is that it lacks a direct blood supply. This means that nutrients and oxygen must diffuse through the cartilage matrix from surrounding tissues, which is a slow process.

3. **Cellular Composition**: While cartilage does contain cells (chondrocytes), it does not have a rich supply of blood vessels. This is important because the healing process often relies on the availability of blood to supply necessary nutrients and remove waste products.

4. **Healing Process**: When cartilage is injured, the lack of blood supply means that the healing process is significantly hindered. The cells in cartilage cannot receive the nutrients they need to repair the tissue effectively.

5. **Conclusion**: Therefore, the reason cartilage heals poorly following an injury is primarily due to the absence of a blood supply.

**Final Answer**: Cartilage heals poorly following an injury because it has no blood supply.
