Which cartilage type is found in the ear and contains abundant elastic fibers?

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

Answer: (C)

Elastic cartilage contains abundant elastic fibers in its matrix, giving it notable flexibility and resilience. This combination is perfect for structures like the external ear, which needs to keep its shape while bending without tearing. In the ear, the auricle is made of elastic cartilage, enabling that pliable yet supportive form. Hyaloid cartilage has mostly type II collagen and less elastic fiber content, providing sturdy but less flexible support. Fibrocartilage is rich in dense collagen fibers, making it very tough and good at resisting compression, not flexible shaping. Bone is mineralized tissue, not cartilage, so it doesn’t apply here.
