Lesson details

Key learning points

  1. Each feature of a synovial joint has a different function.
  2. The cartilage and synovial fluid allow a joint to move freely.
  3. The joint capsule and ligaments help prevent dislocation.
  4. Hinge and ball and socket joints allow different types of movement.
  5. The neck is a pivot joint and the wrist is a condyoid joint.

Keywords

  • Synovial joint - an area where two or more bones meet within a joint capsule and allow a wide range of movement to occur

  • Synovial fluid - fluid secreted by the synovial membrane which lubricates the joint

  • Cartilage - a tough, elastic, fibrous connective tissue that covers the ends of bones to prevent wear and tear

  • Ligaments - a short band of tough and flexible tissue connecting bone to bone to stabilise the joint

  • Tendons - a tough yet flexible band of fibrous tissue which joins muscle to bone

Common misconception

There can be confusion between the role of ligaments and tendons.

Ligaments connect bone to bone to stabilise a joint whereas tendons attach muscle to bone to enable movement.

Being able to analyse the movements possible at specific joints identified by the examination board and recall the definitions of key features at a synovial joint are essential for exam success.
