  1. The characteristics and an example of a synovial joint in humans is:
    1. Characteristics      Examples
      Fluid filled between two joints, provides cushion      Skull bones
    2. Characteristics      Examples
      Fluid filled synovial cavity between two bones      Joint between atlas and axis
    3. Characteristics      Examples
      Lymph filled between two bones, limited movement      gliding joint between carpals
    4. Characteristics      Examples
      Fluid cartilage between two bones, limited movements      Knee joint
Correct Option: B

Synovial joints are characterised by the presence of a fluid filled synovial cavity between the articulating surfaces of the two bones. Such an arrangement allows considerable movement. These joints help in locomotion and many other movements. Ball and socket joint (between humerus and pectoral girdle), Hinge joint (knee joint), Pivot joint (between atlas and axis), Gliding joint (between the carpals) and Saddle joint (between carpal and metacarpal of thumb) are some examples.
