Which cartilage provides support, flexibility, and resilience and is the most abundant type?

• A. Hyaline Cartilage
• B. Elastic Cartilage
• C. Fibrocartilage
• D. Compact Bone

Answer: (A)

Hyaline cartilage provides support, flexibility, and resilience because its matrix is highly hydrated with a network of type II collagen and proteoglycans that cushion joints and allow smooth, gliding movement. This combination makes it strong yet pliable, able to bear loads without cracking. It is the most abundant cartilage in the body and is found at the articular surfaces of joints, as well as in the nose, trachea, and fetal skeleton where it serves as a template for bone growth. Elastic cartilage is more flexible due to elastic fibers but is less abundant and found in structures like the ear and epiglottis. Fibrocartilage is tougher and resists compression, typical of intervertebral discs and menisci. Compact bone is rigid and mineralized, not cartilage, so it doesn’t provide the same flexible support.
