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:
- Olfactory nerve
- Optic nerve
- Oculomotor nerve
- Trochlear nerve
- Trigeminal nerve
- Abducens nerve
- Facial nerve
- Vestibulocochlear nerve
- Glossopharyngeal nerve
- Vagus nerve
- Accessory nerve
- Hypoglossal nerve
So, what's the mneumonic?
There are several, but here are two non-bawdy ones:
On old Olympus towering top a famous vocal German viewed some hops.
Oh! Oh! Oh! to touch and feel very green vegetables AH!.
