Cartilage is the correct answer because it is specifically designed to function as a shock absorber in joints. This connective tissue is flexible and resilient, allowing it to cushion the joints and reduce the impact of stress when bones move against each other.
Cartilage provides smooth surfaces for movement at the joints and serves to protect the underlying bones from damage during activities such as walking, running, or jumping. It has a unique composition, rich in collagen and proteoglycans, which enable it to withstand pressure while maintaining its shape.
Other types of connective tissue have different roles; for instance, fibrous tissue primarily provides strength and support but does not have the cushioning properties of cartilage. Bone is rigid and provides structural support and protection for soft tissues but does not serve as a shock absorber. Adipose tissue mainly acts as fat storage and insulation, playing no role in joint cushioning. Thus, cartilage is uniquely suited for its role in joint function and health.
