These actions evaluate the function of the facial nerve (cranial nerve VII). Puffing out the cheeks tests the motor function of the buccinator muscle, showing the upper and lower teeth tests the motor function of the muscles of mastication, and raising the eyebrows tests the motor function of the frontalis muscle.
