Shelly gives her son an ice-cream cone. The boy grasps the cone with his right hand, opens his mouth, and begins to lick the ice cream. Which muscles does he use to perform these actions?

As the child grasps the ice-cream cone, he uses flexor muscles, principally the flexor digitorum superficialis, flexor digitorum profundus, and flexor pollicis longus muscles. Opening his mouth requires the contraction of the platysma and digastric muscles and the relaxation of the masseter, temporalis, and pterygoid muscles. The licking action would involve the genioglossus muscle (to depress and protract the tongue) and the palatoglossus muscle (to elevate the tongue).
