in the other (the trapezium, a carpal bone of the wrist),
while the other articular surface is reciprocally convex and
concave (the metacarpal bone in the thumb). Thus, the two
bones fit together. Refer to Figure 8-4 to study its
construction. Movement is possible in two planes at

duction and adduction. This construction also permits
opposition of the thumb, an evolutionary advancement
allowing phenomenal dexterity of the hand to grasp and use
tools.
