Which type of connective tissue is described as more flexible than bone and protects the ends of bones?

1. Cartilage

2. Fascia

3. Adipose tissue

4. Ligament

The correct answer is: Cartilage

The correct answer is cartilage because it is a specialized type of connective tissue that provides both flexibility and support to various structures in the body. Cartilage acts as a cushion at the ends of bones, helping to absorb shock during movement and reduce friction when the bones articulate, or move against each other. This protective role is crucial in maintaining the health of joints and ensuring smooth motion. Unlike bone, which is rigid and supportive, cartilage is more pliable, allowing for greater range of motion in areas such as the joints, rib cage, and even the ear and nose. This flexibility makes cartilage particularly well-suited for its protective function at the ends of bones, where it helps to maintain the integrity of the skeletal system while allowing for dynamic activities. Additionally, cartilage is composed of a matrix that includes collagen fibers and other components that contribute to its unique characteristics, making it distinct from other connective tissues like fascia, adipose tissue, and ligaments, each of which has different functions in the body.
