The description fits the Moro reflex, also known as the startle reflex. This reflex is common in newborns and causes them to extend their arms and legs and jerk their head back in response to a sudden noise or movement. It is a normal reflex and typically disappears after a few months. Rooting and grasping reflexes involve different actions with the hands and mouth, and the tonic neck reflex causes the baby to extend one arm and leg and flex the other, not to fling out all limbs.
