Questions from this subtopic
Each one with the model answer underneath.
- 1
How are joints classified by the movement they allow?
Model answer
Fibrous joints allow no movement, and cartilaginous joints allow slight movement. Synovial joints allow free movement.
- 2
What is a fibrous joint?
Model answer
A fibrous joint is a fixed joint where bones are held together by tough fibrous tissue. The sutures of the cranium are an example.
- 3
What is a cartilaginous joint?
Model answer
A cartilaginous joint allows slight movement, with the bones joined by cartilage. The joints between the vertebrae are an example.
- 4
Why are the cartilaginous joints of the spine important to a gymnast?
Model answer
Each joint allows only slight movement, but together they give the spine a large range. The cartilage discs also absorb shock on landing.
- 5
What is a synovial joint?
Model answer
A synovial joint is a freely movable joint enclosed by a joint capsule. The capsule holds synovial fluid that lubricates the joint.
- 6
What are the main features of a synovial joint?
Model answer
A synovial joint has articular cartilage, a joint capsule, a synovial membrane and synovial fluid. Ligaments hold the joint together.
