The ends of some bones are smooth because they form joints. These are referred to as freely moving joints and they are the most common ones in your body. The ends of the bones are smooth because they are covered in hyaline cartilage, which is like soft marble. Inside the joint capsule that contains the ends of the bones with the hyaline cartilage there is a lubricant called synovial fluid that helps the joint move with minimal amount of friction.
