  Which one of the following pair is incorrect? (a) Hinge joint - between humerus and pectoral girdle (b) Pivot joint - between atlas, axis and occipital condyle (c) Gliding joint - between the carpals (d) Saddle joint - between carpel and metacarpals of thumb

Answer:

                  (a) The joint present between humerus and pectoral girdle is ball and socket joint. Hinge joint is present between atlas and axis not between humerus and pectoral girdle.
