Cranial Nerve Functions
by Greg Crowther
The cranial nerves connect to the brain directly, rather than via the spinal cord. There are many mnemonics for learning the cranial nerves' names (e.g., "Oh Oh Oh To Touch And Feel Very Good Velvet -- Ah, Heaven!") and classification as sensory, motor, or both (e.g., "Some Say Money Matters, But My Brother Says Big Brains Matter More"). This song -- originally written for Biology 241 at South Seattle College and UW-Bothell -- complements those mnemonics by adding the additional layer of the function of these cranial nerves. Each nerve is represented as a pitch along a 12-pitch range, with 12 being the highest. Note that functions are similar for nerves VI, IV, and III, so these nerves are grouped together in the song. Also, the functions of nerves II and I come at the end, sort of as an afterthought, because those functions are easy to guess from the names of the nerves (II = optic; I = olfactory).
Twelve; Eleven; Ten; Nine;
Eight; Five; Seven; Six/Four/Three.
Moving your tongue; your back and your neck;
Parasympathetic stuff; saliva and taste.
Balance and hearing; facial senses and chewing;
Adjusting your face; and steering your gaze.
The rest you know well:
There's vision and smell.
• MP3 (by Do Peterson)
• music video
• sheet music (with melody play-back)
Songs like this one can be used during class meetings and/or in homework assignments. Either way, the song will be most impactful if students DO something with it, as opposed to just listening.
An initial, simple follow-up activity could be to answer the study questions below. A more extensive interaction with the song might entail (A) learning to sing it, using the audio file and/or sheet music as a guide, or (B) designing kinesthetic movements ("dance moves") to embody it. The latter activity should begin with students identifying the most important or most challenging content of the song, and deciding how to illustrate that particular content.
(1) According to the song, what is the FUNCTION of each cranial nerve?
(2) Which cranial nerves carry sensory or motor information to or from the eyes?
(3) Which cranial nerves convey gustatory (taste) information?
