Which one of the following options is incorrect ?

Options

A. Hinge joint - between Humerus and Pectoral girdle
B. Pivot joint- between atlas, axis and oc-cipital condyle
C. Gliding joint - between the carpals
D. Saddle joint -between carpal and metac- arpals of thumb

Answer

a

Explanation

Be tween the humeru.s and pectoral girdle is a Ball and Socket joint, not a hinge joint. But as for option (b), be- tween atlasand axis there is a pivot joint. But, between atlas and occipital condyles is a type ofellipsoidal condy- loid joint. This option too is not totally correct. Thus both (a) and (b) are incorrect
