B) Tendon
C) Synovium
D) Articular cartilage

Answer 1

The thin layer of cartilage on the end of bones where they form joints is called articular cartilage. It provides lubrication and reduces friction between bones at a synovial joint.

Step-by-step explanation:

Friction between the bones at a synovial joint is prevented by the presence of the articular cartilage, a thin layer of hyaline cartilage that covers the entire articulating surface of each bone.

Lining the inner surface of the articular capsule is a thin synovial membrane.

The cells of this membrane secrete synovial fluid, a thick, slimy fluid that provides lubrication to further reduce friction between the bones of the joint.

This fluid also provides nourishment to the articular cartilage, which does not contain blood vessels.
