Synovial joints contain synovial fluid. This fluid helps lubricate the joint, reduce friction, and provide nutrients to the joint structures. Examples of synovial joints include the knee, elbow, and shoulder joints.
All synovial joints contain a joint cavity. Synovial joints differ from the other joints: Fibrous and cartilaginous joints. Synovial is different because of its structure, and includes several parts including a joint cavity.

A digit is a finger or toe. Digits contain joints (for example, knuckles) but are not joints themselves.
The articular capsules are found in joints. They contain liquid which lubricates the joints (synovial fluid).

Synovial joints, such as the shoulder and hip joints, have the greatest range of motion and allow for full movement. These joints are surrounded by a synovial membrane that secretes synovial fluid to lubricate and reduce friction during movement.
Fibrous joints connect bones to minimize movement. The bones of your skull and pelvis are held together by fibrous joints. Cartilaginous joints are joints in which the bones are attached by cartilage. These joints allow for only a little movment, such as in the spine or ribs. Synovial joints allow for much more movement than cartilaginous joints. Cavaties between bones in synovial joints are filled with synovial fluid. This fluid helps lubricate and protect the bones. Bursa sacks contain the synovial fluid.
There are three different categories of joints. They are: synarthrotic, amphiarthrotic, and diarthrotic.The synarthrotic joints are mostly immovable and contain cartilage between the bones. An example of these are the suture joints between the cranial bones. Amphiarthrotic joints are a bit more movable and are made of reticular fibers such as those found in the intervertebral discs. The diarthrotic joints are also called synovial joints, or freely moving joints, and comprise the largest group of joints in the human body. These joints are responsible for the overall movement of the body, like the arms and the legs.
Joints are structures in the body where two or more bones come together. They contain connective tissues like ligaments, tendons, and cartilage, as well as synovial fluid, which helps lubricate and cushion the joint. Joints also have a synovial membrane that produces this fluid.
Fibrous joints are immovable and are held together by dense connective tissue. Cartilaginous joints allow limited movement and are connected by cartilage. Synovial joints are freely movable and contain a fluid-filled joint cavity surrounded by a joint capsule.
