WHY is the thumb called the "big finger" if it is the shortest of all? The thumb is opposed to the others; such a position allows us to make varied and precise movements. Only humans are capable of grasping, holding, and masterfully manipulating both large and tiny implements, from a punching machine to a pin. Such diverse functions might be impossible if the thumb were longer or shorter than its actual size. Despite the thumb's seemingly small size - it appears to consist of only two phalanges - it fully lives up to its name, both in importance and size. The muscle responsible for the thumb is the most massive in the palm of the hand. Besides, a special part of the brain, unrelated to the one that controls the actions of the other fingers, coordinates its movements.
