A Synovial joint, also known as a diarthrosis, is the most common and most movable type of joint

Joint

A joint is the location at which two or more bones make contact. They are constructed to allow movement and provide mechanical support, and are classified structurally and functionally.-Classification:...

 in the body of a mammal. As with most other joints, synovial joints achieve movement at the point of contact of the articulating bone

Bone

Bones are rigid organs that constitute part of the endoskeleton of vertebrates. They support, and protect the various organs of the body, produce red and white blood cells and store minerals. Bone tissue is a type of dense connective tissue...

Structural and functional differences distinguish synovial joints from cartilaginous joint

Cartilaginous joint

Cartilaginous joints are connected entirely by cartilage . Cartilaginous joints allow more movement between bones than a fibrous joint but less than the highly mobile synovial joint. An example would be the joint between the manubrium and the sternum...

s (synchondroses and symphyses) and fibrous joint

Fibrous joint

Fibrous joints are connected by dense connective tissue, consisting mainly of collagen.-Types:These joints are also called "fixed" or "immoveable" joints, because they do not move. These joints have no joint cavity and are connected via fibrous connective tissue. The skull bones are connected by...
