| *SHORT ANSWER QUESTION* Shelly gives her son an icecream cone. the boy grasps the cone with his right hand, opens his mouth & begins to lick the icecream. Which muscles does he use to perform these actions? | As the child grasps the icecream cone, he used flexor muscles, principally the flexor digitorum superficialis, flexor digitorum profundus, & flexor pollicis longus muscle. Opening his mouth requires the contraction of the platysma & digastric muscles
🗑

| *CONTINUED*
& the relaxation of the masseter, temporalis & pterygoid muscles. The licking action would involve the genioglossus muscle (to depress/protract the tongue) & the palatoglossus muscle (to elevate the tongue)
