What type of connective tissue serves as a shock absorber for joints?

Cartilage is a specialized form of connective tissue that plays a crucial role in providing support and cushioning for joints. It is a flexible yet durable tissue that can absorb impact, which helps to prevent bone-on-bone friction during movement. This shock-absorbing capability is essential for maintaining joint health, allowing for smooth and pain-free motion.

Cartilage covers the ends of bones where they meet to form joints, such as the knees, hips, and shoulders. Its structure consists of a gel-like matrix rich in water, collagen fibers, and other components, giving it both resilience and the ability to compress under pressure while still returning to its original shape. This makes it an ideal material for absorbing shocks from activities like walking, running, and jumping.

In comparison, bone tissue is rigid and provides structural support but does not have the same shock-absorbing qualities. Adipose tissue serves primarily as fat storage and insulation, lacking the functional characteristics of cartilage. Tendons connect muscles to bones and are designed for strength and stability rather than shock absorption. Hence, cartilage is the correct answer as it specifically fulfills the role of cushioning and protecting joints against shock.
