Tulang Rawan, or cartilage, is a flexible connective tissue found in various parts of the body. It provides support and cushioning in joints, such as the knees and elbows, and is also present in structures like the nose and ears. Unlike bone, cartilage is softer and more pliable, allowing for smooth movement and flexibility. There are three main types of Tulang Rawan: hyaline cartilage, which is the most common and found in joints; elastic cartilage, which provides shape and flexibility, as seen in the ear; and fibrocartilage, which is tough and found in intervertebral discs. Each type serves specific functions in the body.
