Before we discuss about ***Articulation*** more lets we know first the meaning of joint or articulation (or articular surface). The joints are the relationship between the bone and the bone or between the bones and the cartilage. Without joints, bones can not be twisted or bent to produce movement. With the joints the bones can be united with the help of solid connective tissue (ligaments). There is a synovial cirst as a lubricant of movement in the joint.

Based on its function, joints are distinguished by synarthrosis, amphiarthrosis and diarthrosis.

Synarthrosis

Joints that can not be moved at all. This joint is referred to as a dead joint. Synarthrosis is differentiated into synarthrosis of sinfibrosis and synarthrosis of synchondroses.

Synarthrosis of sinfibrosis

Synarthrosis of sinfibrosis for example the joints that exist between the bones of the skull, a sutura. The sutura is a bony, coarse-bony joint connected by a fibrous connective tissue.

Synarthrosis of synchondroses

Synarthrosis of synchondroses is a joint that is linked by cartilage. An example of a synaptic joint of synchondroses is a rib and breast joint linked by hyaline cartilage.

Amphiarthrosis

Amphiarthrosis is Joints whose movements are very limited. For example, at the joints between the vertebral segments connected by fibrous cartilage.

Diarthrosis

Diarthrosis is joints that are free movement. Diarthrosis is also called a living joint. Usually, these joints are present in long bones and have high mobility. Both ends of the bone are covered by cartilage. At the end of this bone there is a cavity filled with synovial fluid. Synovial fluid serves to facilitate movement.
