Which muscle group is responsible for moving the fingers closer together?

The muscle group that is responsible for moving the fingers closer together is the adductors. Adduction refers to the action of bringing body parts closer to the midline or center of the body, and in this case, it pertains to the movement of the fingers. The adductor muscles specifically facilitate this movement by contracting and pulling the fingers towards one another.

The flexors and extensors, while important for finger movement, serve different functions. Flexors are responsible for bending the fingers, which would move them into a hooked position, while extensors straighten the fingers. Abductors, on the other hand, perform the opposite action by moving the fingers away from each other, which is a form of abduction. Therefore, adductors are specifically designated for the movement of fingers coming closer together, making them the correct choice in this context.
