As one author has noted, "Generations of biology and medical students have relied on mnemonic (memory-aiding) phrases and ditties, ranging from sublimely silly to the unprintably ribald, to help them remember the cranial nerves..."[1]
The cranial nerves are:
  • I - Olfactory nerve
  • II - Optic nerve
  • III - Oculomotor nerve
  • IV - Trochlear nerve/pathic nerve
  • V - Trigeminal nerve/dentist nerve
  • VI - Abducens nerve
  • VII - Facial nerve
  • VIII - Vestibulocochlear nerve/Auditory nerve
  • IX - Glossopharyngeal nerve
  • X - Vagus nerve
  • XI - Accessory nerve/Spinal accessory nerve
  • XII - Hypoglossal nerve

[edit]Mnemonics for the nerves

A mnemonic uses, at the least, the first letter of each of the 12 nerves, in order. Examples listed below are those that have been published in textbooks:
  • OOld Olympus' Towering Top, A Finn And German Viewed Some Hops[2] [3][4]
Other variations have been composed more informally by individual persons and propagated to attain widespread notability, such as the ones below:
  • OlOpen Oceans Trouble Tribesmen About FaVentures, Global Vacations, Accusing Hydrophobia
  • Oh, Oh, Oh, TTouch And Feel Virgin Girls Vagina, And Hymen/Hooters

  • Old Officers Often Trust The Army For A Glory Vague And Hypothetical

[edit]Mnemonics for the type of nerve

Mnemonics for the type of nerve or its function rely upon the letters S, M and B for sensory, motor or both. The mnemonics to remember the types of cranial nerves can be chosen from:
S = Sensory
M = Motor
B = Both (sensory + motor)
A common mnemonic for the functions of the first through twelfth nerves, is "Some Say Marry Money, But MBrother Says Big Business Makes Money." [3]
Another common variation of this is "Some Say Marry Money, But MBrother Says Big Brains Matter Most." (or Big/Bouncy Boobs) (or Big Bucks)
  • Some Say Money Matters, But MBrother Says Big Boobs Matter More." (or Bouncy Boobs)
  • Some Say Money Matters, But MBrother Says Baked Brownies Matter Most."
  • Some Say Mind Matters, But MBrother Says Big Boobs Matter More." (or Bouncy Boobs)
  • Silly Superman Made Mortal Brothers Make Bets Since Both Boys Made Money"
  • Some Say Money Matters, But MBeloved Says Being Beloved Matters More."

Or to include the three Trigeminal branches: Some say money matters, some say banks, my brother says big brains matter most.
