The structure of a synovial joint

Question 1

The bones at a synovial joint

Answer 1

1) The bones at a synovial joint are held together by ligaments.
2) The ends of the bones are covered with cartilage and are shaped so that they fit together and can move smoothly.
3) Synovial joints have synovial fluid in the joint cavity that lubricates or ‘oils’ the joint so it moves smoothly.

Question 2

The synovial membrane

Answer 2

It releases synovial fluid into the joint capsule to lubricate (or ‘oil’) the joint, allowing it to move easily.

Question 3

What does the synovial joint allow us to do?

Answer 3

Allows us the free movement to perform skills and techniques during physical activity.

Question 4

What is a joint?

Answer 4

A joint is where two or more bones meet and is also called articulation.

Question 5

What are ligaments?

Answer 5

Are a type of connective tissue and are tough, fibrous and slightly elastic.
They connect bone to bone and help keep the joint together.
They stabilise the joints during movement and prevent dislocation by restricting actions outside the normal joint range.
They can absorb shock because of their elasticity, which protects the joint.
They help maintain correct posture and movement.
