types of joints
A joint is a point where two or more bones meet. There are three main types of joints; Fibrous (immovable), Cartilaginous (partially moveable) and the Synovial (freely moveable) joint.
- Synovial (diarthrosis): Synovial joints are by far the most common classification of a joint within the human body.
- They are highly moveable and all have a synovial capsule (collagenous structure) surrounding the entire joint, a synovial membrane (the inner layer of the capsule) which secretes synovial fluid (a lubricating liquid) and cartilage known as hyaline cartilage which pads the ends of the articulating bones.
- There are 6 types of synovial joints which are classified by the shape of the joint and the movement available.
