12 Cranial Nerves

As part of learning how the brain's 12 cranial nerves are organized, you'll have to learn the names and functions of each. Luckily, a simple mneumonic device has been devised to help students of anatomy and later courses such as neurology to memorize them. It's crude but it helps.

But first, what is the sequence? The twelve nerves are: OOOTTAFVGVAH, meaning:

  1. Olfactory nerve
  2. Optic nerve
  3. Oculomotor nerve
  4. Trochlear nerve
  5. Trigeminal nerve
  6. Abducens nerve
  7. Facial nerve
  8. Vestibulocochlear nerve
  9. Glossopharyngeal nerve
  10. Vagus nerve
  11. Accessory nerve
  12. Hypoglossal nerve

So, what's the mneumonic?

There are several, but here are two non-bawdy ones:

German
On old Olympus towering top a famous vocal German viewed some hops.

Vegan
Oh! Oh! Oh! to touch and feel very green vegetables AH!.
