What It Is?

Cartilage is a tough but flexible connective tissue that cushions joints. It's made of cells called chondrocytes, which produce an extracellular matrix composed of collagen and proteoglycans.

Why It's Important?

Cartilage is a type of connective tissue that supports the structure of many animals' bodies and skeletons. It is made up of cells called chondrocytes, which produce a gel-like substance called hyaluronan that acts as a shock absorber and lubricant. Hyaluronan helps reduce friction between two surfaces as well as helping to retain water in tissues. A group of chondrocytes known as an osteoarthritic nodule may appear under a microscope when cartilage is damaged by disease or injury.

Additional info?

Cartilage has anti-cancer properties because it inhibits the growth of blood vessels around tumors, preventing them from spreading throughout the body.
