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 bursae works as a cushion to reduce friction as we move at a joint.

Keywords

• Synovial joint - an area of the body where two or more bones meet (articulate) to allow a range of movements

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

• Cartilage - strong connective tissue that acts a buffer between bones; absorbing shock and preventing friction on the end of bones

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

• Tendons - strong, flexible tissue that attaches muscle to bone
