A joint, or articulation , is the place where two bones come together.
Immovable joints are synarthroses .
In this type of joint, the bones are in very close contact and are separated only by a thin layer of fibrous connective tissue. An example of a synarthrosis is the suture in the skull between skull bones. Slightly movable joints are called amphiarthroses . The ribs that connect to the sternum are an example of an amphiarthrosis joint. Most of the joints in the adult human body are freely movable joints.
