Which type of tissue covers the surfaces of bones to reduce friction?

• A. Muscle
• B. Epithelium
• C. Cartilage
• D. Connective

Answer: (C)

The type of tissue that covers the surfaces of bones to reduce friction is cartilage. This specialized connective tissue is smooth and resilient, allowing for easy movement at joints where bones meet. Cartilage forms a protective layer on the ends of long bones and provides a cushioning effect that minimizes friction between the bones as they articulate during movement. Its structure is designed to withstand compressive forces and contribute to the overall stability and function of the skeletal system.

In joints, such as the knee or elbow, cartilage not only reduces friction but also absorbs shock and enables a wide range of motion. Understanding the role of cartilage is essential in fields like healthcare and fitness, where joint health is a key aspect of overall well-being.
