Kıkırdak, 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, kıkırdak is softer and more pliable, allowing for movement and flexibility. Kıkırdak is composed of cells called chondrocytes, which are embedded in a gel-like matrix made of collagen and elastin fibers. This unique structure enables kıkırdak to absorb shock and reduce friction between bones during movement. It plays a crucial role in the overall function of the skeletal system.
