Gross control means the ability to make large, general movements (such as waving an arm or lifting a leg). It requires proper coordination and function of muscle, bones, and nerves.
Gross control is a milestone in the development of an infant.
Infants develop gross motor control before they develop the ability to make small, precise movements. See: Fine motor control
