dexterous

Any of the motor skills that require greater control of the small muscles than large ones, esp. for hand-eye coordination or for precise hand and finger movement. Fine motor skills include handwriting, sewing, and fastening buttons. Most movements require both large and small muscle groups, and there is considerable overlap between fine and gross motor skills, but distinguishing between the two is useful in rehabilitation settings, special education, adapted physical education tests, motor development tests, and aptitude tests in industry and in the military .
