Concept essentials

  • Synovial fluid lubricates joints and reduces friction.
  • Cartilage cushions bone ends and allows smooth movement.
  • Ligaments connect bones to bones and stabilise joints.
  • Tendons transmit muscle contraction force to bones.
  • Joint capsules help seal the joint and retain synovial fluid.
