What is the primary function of cartilage in joints?

  1. Facilitates nerve communication

  2. Cushions joints and prevents wear

  3. Connects muscles to bones

  4. Transmits electrical signals

The correct answer is: Cushions joints and prevents wear

The primary function of cartilage in joints is to cushion the joints and prevent wear. Cartilage is a flexible connective tissue found in various parts of the body, especially at the ends of bones in joints. Its smooth surface allows for frictionless movement, enabling bones to glide over one another during movement. This cushioning effect not only absorbs shock but also protects the underlying bones from damage during high-impact activities. Additionally, by distributing loads and reducing stress on the joints, cartilage plays a crucial role in maintaining joint health and function throughout a person's life.
