Kraakbeenweefsel

Kraakbeenweefsel, also known as cartilage, is a flexible connective tissue found in many areas of the body, including joints, ears, nose, and intervertebral discs. It is composed of specialized cells called chondrocytes, which are embedded in a matrix of collagen and proteoglycans. This matrix gives cartilage its strength and resilience, allowing it to withstand significant stress and compression.

There are three main types of cartilage, each with distinct properties and functions. Hyaline cartilage, the most common type, is found in the articular surfaces of bones in joints, the rib cage, and the trachea. It provides a smooth, low-friction surface for movement and helps to absorb shock. Elastic cartilage, found in the external ear and epiglottis, contains elastic fibers that allow it to return to its original shape after being stretched or compressed. Fibrocartilage, the strongest type, is present in the intervertebral discs, menisci of the knee, and pubic symphysis. It provides cushioning and shock absorption while maintaining structural integrity.

Cartilage lacks blood vessels, which means it has a limited capacity for self-repair. Damage to cartilage, such as that caused by injury or osteoarthritis, can therefore be slow to heal and may lead to chronic pain and joint dysfunction. Treatments for cartilage damage often focus on managing symptoms, slowing disease progression, or, in some cases, surgical interventions like cartilage transplantation.
