A joint or articulation (or articular surface) is the connection made between bones in the body which link the skeletal system into a functional whole.They are constructed to allow for different degrees and types of movement. Some joints, such as the knee, elbow, and shoulder, are self-lubricating, almost frictionless, and are able to withstand compression and maintain heavy loads while still executing smooth and precise movements. Other
joints such as sutures between the bones of the skull permit very little movement (only during birth) in order to protect the
brain and the sense organs. The connection between a tooth and the jawbone is also called a joint, and is described as a fibrous joint known as a gomphosis.
Joints are classified both structurally and functionally. Damaging the cartilage of
joints (articular cartilage) or the bones and muscles that stabilize the
joints can lead to joint dislocations and osteoarthritis. Swimming is a great way to exercise the
joints with minimal damage.A joint disorder is termed arthropathy, and when involving inflammation of one or more
joints the disorder is called arthritis. Most joint disorders involve arthritis, but joint damage by external physical
trauma is typically not termed arthritis.
