Quizplus · Accepted Answer

The joint between the metacarpal of the thumb and the trapezium is a saddle joint. This type of joint allows for a wide range of movement, including opposition of the thumb, where the thumb can move across the palm of the hand to touch the tips of the fingers. This movement is essential for tasks such as grasping objects and holding utensils. The other options (pivot, condyloid, plane, and ball-and-socket) are not suitable for this joint as they do not allow for the required movement.
