Question

Quizplus · Accepted Answer

Opposition is the movement of the thumb as it moves toward the little finger, allowing the thumb to touch the tips of the other fingers. This movement is unique to the thumb and is important for grasping objects and performing fine motor skills. Pronation is the movement of rotating the forearm so that the palm faces downward, while eversion is the movement of turning the foot so that the sole faces outward. Circumduction is a circular movement that combines flexion, extension, abduction, and adduction, while excursion refers to the distance traveled by a muscle or joint. None of these movements involve the thumb moving toward the little finger in the way that opposition does.
