Cranial Nerve 9 (Glossopharyngeal)
How is Cranial Nerve 1 (Olfactory) assessed?
Eyes are closed, and patient asked to identify smells (coffee, vanilla, cinnamon).
How is Cranial Nerve 4 (Trochlear) assessed?
Asking the patient to follow the six EOM (Extra Ocular Movements)

Use of tuning fork.
Heel-Toe walking in straight line.
How is Cranial Nerve 9 (Glossopharyngeal) assessed?
Swallowing water. Applying tastes (Sweet, Salty, Bitter, Sour) to posterior tongue.
How is Cranial Nerve 12 (Hypoglossal) assessed?
Ask pt to stick out tongue (should be midline).
Ask pt to move tongue side-side and up-down.
How is Cranial Nerve 6 (Abducens) assessed?
Six EOM (Extra Ocular Movements)
How is Cranial Nerve 5 (Trigeminal) assessed?
Pt closes eyes, identifies touch.
Eye drop to test for blink reflex.
Ask pt to clench teeth.
How is Cranial Nerve 7 (Facial) assessed?
Ask pt to: smile, frown, show teeth, close both eyes, puff cheeks, whistle, raise eyebrows.
Test for taste on anterior 2/3 of tongue.
How is Cranial Nerve 11 (Accessory) assessed?
