Final answer:
Articular cartilage is a thin layer of hyaline cartilage on the epiphysis that reduces friction and absorbs shocks at synovial joints.
Step-by-step explanation:
A thin layer of hyaline cartilage covering the part of the epiphysis where the bone forms an articulation with another bone is known as articular cartilage. This specific tissue is crucial for joint function, as it serves to reduce friction and act as a shock absorber during movements. Articular cartilage ensures that the articulating surfaces of bones in a synovial joint can move smoothly against each other, preventing the bones from grinding directly on one another and avoiding damage to the bone tissue
