The main function of cartilage is to provide support and cushioning in joints. It acts as a smooth, lubricated surface that allows bones to move freely against each other without friction.
Cartilage also plays a crucial role in:
- Resisting compressive forces: This is especially important in weight-bearing joints like the knees and hips.
- Enhancing bone resilience: Cartilage helps to absorb shock and protect bones from damage.
- Providing support in bony areas where flexibility is needed: This is seen in the nose, ears, and trachea.
The primary cell type in cartilage is the chondrocyte, which produces and maintains the cartilage matrix.
