Which connective tissue structure acts as a shock absorber in synovial joints?

The connective tissue structure that acts as a shock absorber in synovial joints is articular cartilage. This smooth, white tissue covers the ends of bones where they come together to form joints. It serves multiple important functions, including reducing friction during movement and distributing loads across the joint surfaces, thereby absorbing shock when forces are applied to the joint.

Articular cartilage is crucial for joint health and functionality, as it helps prevent bone-on-bone contact, which can cause pain and damage. Additionally, because it is avascular (lacking blood vessels), articular cartilage relies on the synovial fluid within the joint for nourishment and to maintain its integrity. This special structure allows for smoother movements and greater resilience, making it an essential component for joint stability and durability.
