Which type of cartilage is found at the ends of long bones?

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

Answer: (C)

The correct type of cartilage found at the ends of long bones is hyaline cartilage. This cartilage is smooth, glassy, and provides a low-friction surface for joints, allowing for easy movement between the bones. It plays a crucial role in joint function and is located in various parts of the body, including the articular surfaces of bones where they come together to form joints. Hyaline cartilage is also important during the growth of long bones in children and adolescents, as it contributes to the growth plates, also known as epiphyseal plates. These plates help in the elongation of bones as they grow. Other types of cartilage have different structures and functions; for instance, elastic cartilage contains a higher density of elastin fibers and is more flexible, which is why it is found in structures like the ear. Fibrocartilage is tougher and is designed to withstand compressive forces, commonly found in intervertebral discs and the menisci of the knee. Meanwhile, intervertebral cartilage specifically refers to the fibrocartilage located between vertebrae, serving a different purpose than hyaline cartilage.
