GCSE PE UNIT 1 - joints

• A joint is the place where two or more bones meet
• Synovial joints are joints filled with fluid that surrounds cartilage

  attached at the end of each of the bones that meet at the joint.
• The structure of synovial joints is designed to reduce the risk of injury

  by containing:

  A tough capsule that surrounds the joint, lined by a synovial

  membrane.

  Ligaments joining bones to bones which prevent unnecessary

  movements and dislocations.

  Synovial fluid that lubricates the joint is created in the capsule

  which reduces friction and wear of the joint.

  Further small bags of synovial fluid, known as bursae, also

  surround the joint to prevent friction from the movement of

  tendons across the surface of the joint.
• There are 6 types of synovial joints
