The 12 Cranial Nerves Made Easy

Understanding the human body can be complex, especially when it comes to the cranial nerves. However, I’m here to simplify it for you in the easiest way possible, regardless of whether you’re a medical practitioner or someone with little medical knowledge. Let’s dive in and explore the 12 cranial nerves using a simple mnemonic!

Mnemonic: “On Old Olympus Towering Tops, A Finn And German Viewed Some Hops”

Now, let’s break down the mnemonic and associate it with each of the 12 cranial nerves:

1. Olfactory (CN I)

The first cranial nerve is the olfactory nerve. Think of the “O” in “Old” from our mnemonic. This nerve is responsible for our sense of smell.

2. Optic (CN II)

The second cranial nerve is the optic nerve. The “O” in “Olympus” helps us remember this one. The optic nerve is crucial for vision.

3. Oculomotor (CN III)

The third cranial nerve is the oculomotor nerve. The “O” in “Towering” represents this nerve. It controls the movement of the eye muscles.

4. Trochlear (CN IV)

The fourth cranial nerve is the trochlear nerve. The “T” in “Towering” helps us recall this one. It also controls eye movement.

5. Trigeminal (CN V)

The fifth cranial nerve is the trigeminal nerve. The “A” in “And” represents this nerve. It is responsible for facial sensation and chewing.

6. Abducens (CN VI)

The sixth cranial nerve is the abducens nerve. The “F” in “Finn” helps us remember this one. It controls the lateral movement of the eye.

7. Facial (CN VII)

The seventh cranial nerve is the facial nerve. The “A” in “And” represents this nerve as well. It controls facial expressions and taste sensation.

8. Vestibulocochlear (CN VIII)

The eighth cranial nerve is the vestibulocochlear nerve. The “G” in “German” helps us recall this one. It is responsible for hearing and balance.

9. Glossopharyngeal (CN IX)

The ninth cranial nerve is the glossopharyngeal nerve. The “V” in “Viewed” represents this nerve. It controls swallowing and taste sensation.

10. Vagus (CN X)

The tenth cranial nerve is the vagus nerve. The “S” in “Some” helps us remember this one. It is responsible for various functions such as heart rate, digestion, and vocalization.

11. Accessory (CN XI)

The eleventh cranial nerve is the accessory nerve. The “H” in “Hops” helps us recall this one. It controls the movement of the neck and shoulders.

12. Hypoglossal (CN XII)

The twelfth cranial nerve is the hypoglossal nerve. The “H” in “Hops” represents this nerve as well. It controls tongue movement.

And there you have it! By using the mnemonic “On Old Olympus Towering Tops, A Finn And German Viewed Some Hops,” you can easily remember the 12 cranial nerves. Whether you’re a medical professional or someone with little medical knowledge, this simplified approach makes it easy to recall these important nerves. Happy learning!
