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

Cartilage is the type of connective tissue that functions as a shock absorber for joints. Its unique composition, which includes a high water content and a gel-like matrix, allows it to withstand pressure and provide cushioning between the bones at the joints. This structure helps to reduce friction during movement and protects the underlying bones from impact, which is particularly important in areas such as the knee, hip, and spine. The resilience and flexibility of cartilage enable it to absorb forces that occur during activities such as walking, running, and jumping, promoting joint health and mobility.

Other types of connective tissue, like bone, serve primarily to provide structure and support to the body. Adipose tissue, while important for energy storage and insulation, does not have the same shock-absorbing properties. Tendons connect muscles to bones and are designed to transmit forces rather than absorb shocks. Thus, cartilage is specifically designed to fulfill the role of a shock absorber in joints, making it the correct answer.
