A joint is a junction (articulation) between two or more bones |
| A fibrous or fixed joint is an immovable joint in which bones are held together by connective tissue |
Fibrous joints are found where it is important to have joints which do not allow any movement so that bones can be connected to form rigid, supporting structures |
Give an example of a fibrous joint. Between bones of the skull / between teeth and jaws |
A cartilaginous joint allows limited movement. The bones are held together by interposed cartilage fastened to the bones by connective tissue |
Name TWO sites in the body where there are cartilaginous joints. Between adjacent vertebrae / between coxal bones / ribs and sternum |
| A synovial joint is a freely moveable joint in which bones are bound together by ligaments and connective tissue forming a fluid-filled joint cavity. In the joint cavity, ends of bones are covered in articular cartilage. An outer articular capsule helps to maintain bone alignment while an elastic synovial membrane secretes and contains the lubricating synovial fluid. |
