Which type of cartilage is the most abundant in the body?

• A. Elastic cartilage
• B. Fibrocartilage
• C. Articular cartilage
• D. Hyaline

Answer: (D)

Hyaline cartilage is the most widespread type because its glassy, well-hydrated matrix provides a sturdy yet smooth and flexible support for many structures. The matrix is rich in type II collagen and proteoglycans, which gives it the resilience needed to cushion joints and resist compression while still allowing easy movement. This makes it ideal for covering joint surfaces as articular cartilage, shaping the nose, forming the walls of the trachea and bronchi, and constituting the costal cartilages that connect ribs to the sternum. It also forms most of the fetal skeleton, with much of it persisting in various form in adulthood. Other cartilage types are more specialized. Elastic cartilage adds elastic fibers for greater flexibility and is found in the ear and epiglottis, while fibrocartilage is tougher and more resistant to shear and compression, located in intervertebral discs, the pubic symphysis, and the menisci. These areas are fewer in number compared with the broad distribution of hyaline cartilage.
