our joints, which are made up of mainly cartilage.
Those sac-like structures are called bursae. They contain a small amount of fluid to help reduce friction and provide cushioning between tissues such as muscles, tendons, and bones.
Cartilage in joints REDUCE friction.
Yes, it does, since it acts as a cushion between the bones
Synovial fluid reduces friction between bones at joints. It is a lubricating fluid secreted by the synovial membrane and contains hyaluronic acid and lubricin to facilitate smooth movement between bones.
Cartilage
Articular surfaces of bones are smooth bony projections that are designed to articulate with another bone, forming a joint. These surfaces are covered with cartilage to reduce friction and allow for smooth movement. Examples include the femoral head articulating with the acetabulum in the hip joint.

The carpals articulate distally with the ulna. The carpals are also known as the wrist bones.
No, most facial bones do not articulate with the mandible. The mandible primarily articulates with the temporal bones at the temporomandibular joint, while the rest of the facial bones are connected by sutures and ligaments.
