joint

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.

    Leaking joint on Aluminium radiators

    Hi, Where the valves screw into the aluminium rads has started to leak (all be it not that much). The system is a ordinary pressurised sealed system. The leak is hardly enough to drop the pressure. The system has been fine for 4yr+, I guess that the rubber gasket has started to fail. I have...
