Want to learn how to memorize the cranial nerves? Cranial nerve mnemonics can turn a long list of medical terms into a sequence you can remember.
In this detailed article you will find various mnemonics to help you recall the names and functions of the 12 cranial nerves fast and easy.
What are Cranial Nerves ?
Cranial nerves are the behind the scenes heroes of our nervous system. They allow us to experience the world through our senses and enable movements of the eyes, tongue, mouth and face.
From smelling a rose to facial expressions, cranial nerves are involved in everything we do.
These nerves are responsible for sensory experiences like seeing, hearing, smelling and tasting and facial movement. They manage sensory processing, motor control and autonomic regulation.
Cranial nerves are vital for our nervous system to function properly.
And while cranial nerves mainly originate from the brain, some like the accessory nerve also have origins in the spinal cord, showing how these structures are connected in the peripheral nervous system.
If you notice any sudden changes in your senses or facial functions, see a healthcare provider. Cranial nerves are part of our nervous system and any disruption can affect our daily life.
Cranial Nerve Functions
Cranial nerves manage many functions, from sensory perception to motor control.
They mainly manage sensory and motor functions in the head and neck, including motor nerves, so they are the focus during neurological exams.
For example the trigeminal nerve has 3 branches, provides sensory input from different facial regions and controls the muscles used for chewing.
Beyond the basic sensory and motor functions, cranial nerves also manage complex activities. The oculomotor nerve for example not only controls eye movement but also pupil size and ability to focus on near or far objects.
This shows how important it is to know cranial nerve functions in detail.
How many Cranial Nerves?
There are 12 pairs of cranial nerves, each with its own set of functions.
They are paired and labeled from I to XII from front to back of the brain.
This labeling system makes it easy to identify and study each nerve.
Cranial Nerve Mnemonics
Mnemonics are more than just silly phrases; they are memory retention superpowers. When it comes to cranial nerves a cranial nerve mnemonic can turn a long list into a sequence you can remember.
Suppose recalling all 12 cranial nerves in one go, just by remembering a fun and catchy phrase.
One of the most popular mnemonics for cranial nerves is ‘Oh Oh Oh To Touch And Feel Very Good Velvet AH’.
Each word in this phrase represents the first letter of a cranial nerve, making it easy to remember the names and order.
These mnemonic tricks can be fun and effective, making memorization a breeze.
You can create your own mnemonics to make it even more personalized and effective. Create a phrase using the first letter of each cranial nerve and make it your own.
Add humor or context and make it more relatable and easier to remember.
Mnemonics
One of the most common cranial nerve mnemonic is ‘Oh, Oh, Oh, To Touch And Feel Very Good Velvet, AH!’. Each word represents the first letter of a cranial nerve.
Mnemonics like these are memory aids to help you recall lists such as the names of the cranial nerves. They make learning easier and more fun, turns memorization into a game.
Personalized Mnemonics
When creating personal mnemonics use the first letter of each cranial nerve to create a phrase or sentence.
For example, you can come up with something like ‘On Old Olympus’ Towering Top, A Friendly Viking Grew Violets And Hops’ to remember the cranial nerves.
Personalized mnemonics can be made more effective by adding humor or context. This makes them more relatable and easier to remember, makes learning fun.
Mnemonics for Cranial Nerve Functions
Just as mnemonics can help you remember cranial nerve names, they can also be very useful in recalling their functions.
Linking names with their functions makes mnemonic devices a powerful learning tool.
A common mnemonic to classify cranial nerves as sensory, motor or both is ‘Some Say Money Matters, But My Brother Says Big Brains Matter More’.
This helps you quickly identify the type of each cranial nerve and makes it easier to remember their functions.
Functional mnemonics link mnemonics for cranial nerve names with those for their functions, making it a single learning tool.
For example ‘Oh Oh Oh To Touch And Feel Very Good Velvet AH’ can be linked with functional mnemonics to reinforce memory.

Sensory, Motor or Both
Cranial nerves can have sensory functions for sight, smell and hearing and motor functions for muscle movements.
The optic nerve for example transmits visual information from the retina to the brain.
A common mnemonic to classify cranial nerves as sensory, motor or both is ‘Some Say Marry Money But My Brother Says Big Brains Matter More’.
This makes classification easier and quicker to recall.
Functional Mnemonic Phrases
One of the most popular mnemonic for cranial nerves is ‘On old Olympus’s towering top a Finn and German viewed some hops’.
Of course, This phrase helps you remember the cranial nerves and their functions.
Writing both mnemonics side by side helps you memorize cranial nerve names and functions together. This dual approach reinforces memory and makes learning more efficient.
Personal Cranial Nerve
Now that we’ve covered mnemonics for cranial nerve names and functions, let’s take a look at each cranial nerve.
Knowing the functions and mnemonics for each nerve will make learning and recall even easier.
Olfactory Nerve (CN I)
The olfactory nerve (CN I) is for the sense of smell. A simple mnemonic is ‘Olfactory – Old Factories smell’. This makes it easy to remember.
Optic Nerve (CN II)
The optic nerve (CN II) is for vision. A mnemonic is ‘Optic – Optics for vision’. This links the function to the name.
Oculomotor Nerve (CN III)
The oculomotor nerve (CN III) controls most of the eye movements including raising the eyelid and adjusting the size of the pupil.
A mnemonic is ‘Oculomotor – Motor for eyes’.
Trochlear Nerve (CN IV)
The trochlear nerve (CN IV) controls the superior oblique muscle which is responsible for downward and lateral motion of the eye. A mnemonic is ‘Trochlear – Pulley (eye muscle)’.
Trigeminal Nerve (CN V)
The trigeminal nerve (CN V) is for facial sensation and chewing. It has three branches and a mnemonic is ‘Trigeminal – Tri (three branches)’.
Abducens Nerve (CN VI)
The abducens nerve (CN VI) controls the lateral rectus muscle which moves the eye outward. A mnemonic is ‘Abducens – Abducts the eye’.
Facial Nerve (CN VII)
The facial nerve (CN VII) is for facial expressions and carries taste sensations from the front of the tongue. A mnemonic is ‘Facial – Face expressions’.
