This photo shows Cranial Nerve 12 Dysfunction: Stroke has resulted in loss of function of left CN 12. When patient sticks tongue out, it therefore deviates to the left.
Assessment is performed as follows:•Ask the patient to stick their tongue straight out of their mouth.
•If there is any suggestion of deviation to one side/weakness, direct them to push the tip of their
tongue into either cheek while you provide counter pressure from the outside.
