  1. The characteristics and an example of a synovial joint in humans are
    Characteristics Examples
    (a) Fluid-filled between two joints, provides cushion Skull bones
    (b) Fluid-filled synovial cavity between two bones Joint between atlas and axis
    (c) Lymph filled between two bones, limited movement Gliding joint between carpals
    (d) Fluid cartilage between two bones, limited movements Knee joint

(b) Fluid-filled synovial cavity between two bones Joint between atlas and axis

  1. Out of ‘X’ pairs of ribs in humans only ‘Y’ pairs are true ribs. Select the option that correctly represents values of X and Y and provides their explanation.
    (a) X = 12, Y = 5
    True ribs are attached dorsally to the vertebral column and sternum on the two ends.
    (b) X = 24, Y = 7
    True ribs are dorsally attached to the vertebral column but are free on the ventral side.
    (c) X = 24, Y = 12
    True ribs are dorsally attached to the vertebral column but are free on the ventral side.
    (d) X = 12, Y = 7
    True ribs are attached dorsally to the vertebral column and ventrally to the sternum.

(d) X = 12, Y = 7 True ribs are attached dorsally to the vertebral column and ventrally to the sternum.
