the ends of the bones are, yes

Most joints of the body are synovial joints, which are characterized by the presence of a synovial fluid-filled joint cavity. These joints allow for a wide range of movement due to the presence of articulating surfaces covered in hyaline cartilage and reinforced by ligaments. Examples include the knee, shoulder, and hip joints.
Articular cartilage is cartilage which covers the surface of the bone in synovial joints. Its function is to reduce friction between the bones. It is a type of cartilage called hyaline cartilage.
In symphysis joints, the articular surfaces of the bones are covered with hyaline cartilage and fibrocartilage. The fibrocartilage acts as a shock absorber and provides stability to the joint while the hyaline cartilage allows for smooth movement between the bones.
Hyaline cartilage normal covers the articular surfaces of bones in typical synovial joints and primary cartilaginous joints. Certail joints do not have hyaline cartilage covering the bony elements. These include: 1. Fibrous Joints - skull sutures, gymphosis (teeth) and interosseus joints (radius and ulna shafts) 2. Atypical Synovial Joints (these have fibrocartilage instead of hyaline cartilage covering the bones). These include the Temporomandibular (TMJ), Acromioclavicular Joint (ACJ), Sternoclavicular Joint, and 2nd to 7th Sternocostal Joints.
The periosteum provides nourishment and attachment sites on bone. Since the ends of bones in synovial joints are covered in hyaline cartilage, they do not need to be covered by the protective layer of periosteum.
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.
hyaline cartilage A Hyaline cartilage, but lacking perichondrion
Light micrograph of hyaline cartilage is a flexible connective tissue. This is including the joints between bones. To maintain this, one would need to take glucosamine chondroitin or something similar.
Hyaline is the most common type of cartilage.
The epiphyses of long bones are covered by hyaline cartilage, also known as articular cartilage. This cartilage provides a smooth surface for articulation at the joints and helps reduce friction during movement.
