Ever have one of those nights before a test when you get something inane stuck in your head and you can’t sleep?
Yeah…having one of those.
Anyhow, I decided to make it useful and create a wretched little ditty to memorize cranial nerve assessment. Figured I might as well share it with any other nursing students out there (I know there are several on the Dope). Or, if not, at least typing it here will help me to study!
One nose to smell
Two eyes to see well
Three, four six
make your eyes do tricks
Forehead, cheek and chin
Five will do you in
Seven is the question
Can you make expressions?
Eight, can you hear
in both your ears?
Nine would gag Apollo
Ten will help him swallow,
Then with nerve eleven
raise shoulders up to heaven
“Light” and “tight”
twelve will get it right!
(“Three, four six, makes your eyes do tricks” is the not-original piece of this ditty that woke me up stuck in my head. I decided to write the rest around it.)
I - Olfactory nerve, controls the sense of smell
II - Optic nerve, controls vision
III - Oculomotor, moves eyelids down and helps the eyes converge to focus on a near object
IV - Trochlear nerve, moves eyes down to nose
VI - Abducens nerve, moves eyes to the sides
V - Trigeminal nerve, sensation (and a little movement) of the jaw, forehead and chin
VII - Facial nerve, the main motor nerve of the whole face, controls muscles needed to frown, smile, make and angry face, etc.
VIII - Acoustic nerve, controls hearing
IX - Glossopharyngeal nerve, controls gag reflex
X- Vagus nerve, controls smooth swallowing
XI - Spinal accessory nerve, controls shoulders’ upward movement
XII - Hypoglossal nerve, controls the tongue; to test, ask pt. to say “light and tight”
There’s a little dance to go along with it, but I think I’ll spare you and try to go back to bed now!
