Joints, also referred to as
articulations, act as junctions
between bones and vary widely in structure and function. They are classified
both as to how they move and according to the types of tissue that binds bones
together at the joint. The two primary functions of joints are to hold the
skeleton together (which offers a certain amount of protection) and to make the
skel-eton mobile. However, they are the weakest compo-nents of the skeleton.
They resist tearing, crushing, and other forces that are able to force them out
of alignment.
