title: [Aspects of finger mobility].
abstract: The movements of the finger, centrally induced and controlled via open or closed loops, need the simultaneous action of several muscles and muscle groups. In this way, rigid differentiation between antagonists and synergists is functionally abolished. Synchronous flexion and extension of a finger needs not only a palmar flexion and a dorsal extension motor system but also a third oblique running motor system. This is given by the interosseous-lumbricalis system. Opposition and repositioning of the thumb require muscle configuration other than that provided by the other fingers.
