Dear you welcome to the captivating world of cranial nerves! In our journey through the intricacies of the human body, the cranial nerves emerge as true wonders. These 12 nerves, each with its own specific role, can be challenging to remember. But fret not, for we have a little memory aid up our sleeves – mnemonics!
Let's embark on this adventure of discovery and mnemonic mastery to make these cranial nerves stick in our minds like never before. just read and you will find below a lot of pictures that made it easy for you to remember them.
Olfactory (CN I)
Olfactory (CN I) - "Oh, Oh, Oh, To Touch And Feel Very Green Vegetables, AH!"
Our journey begins with the olfactory nerve, responsible for our sense of smell. Picture this: "Oh, Oh, Oh, To Touch And Feel Very Green Vegetables, AH!" - a vivid mnemonic that effortlessly helps us remember that this is the first cranial nerve (CN I). Each word corresponds to a cranial nerve, from "Oh" for Olfactory to "AH" for Hypoglossal.
Optic (CN II)
Optic (CN II) - "Optic Nerve Is Notably Sensory"
Moving on to the optic nerve (CN II), which is all about vision. Remember it as "Optic Nerve Is Notably Sensory" to emphasize its sensory function.
Oculomotor (CN III), Trochlear (CN IV), Abducens (CN VI)
Oculomotor (CN III), Trochlear (CN IV), Abducens (CN VI) - "Some Say Marry Money, But My Brother Says Big Brains Matter More"
Now, we delve into the trio of cranial nerves responsible for controlling eye movements: Oculomotor (CN III), Trochlear (CN IV), and Abducens (CN VI). Simply recite the phrase "Some Say Marry Money, But My Brother Says Big Brains Matter More" to effortlessly remember their order and abbreviations.
Trigeminal (CN V)
Trigeminal (CN V) - "The Trigeminal Nerve: Three Sensory Branches"
The trigeminal nerve (CN V) boasts three sensory branches: V1 (ophthalmic), V2 (maxillary), and V3 (mandibular). Remember it with "The Trigeminal Nerve: Three Sensory Branches."
Facial (CN VII)
Facial (CN VII) - "Facial Nerve: Funny Taste, Bell's Palsy, Tears"
For the facial nerve (CN VII), linked to facial expressions and taste from the anterior two-thirds of the tongue, recall the mnemonic "Facial Nerve: Funny Taste, Bell's Palsy, Tears."
Vestibulocochlear (CN VIII)
Vestibulocochlear (CN VIII) - "Vestibulocochlear Nerve: Balance and Hearing"
The vestibulocochlear nerve (CN VIII) plays a dual role in balance and hearing. Engrave it in your memory with "Vestibulocochlear Nerve: Balance and Hearing."
Glossopharyngeal (CN IX)
Glossopharyngeal (CN IX) - "Glossopharyngeal: Gag Reflex and Swallowing"
As for the glossopharyngeal nerve (CN IX), responsible for the gag reflex and swallowing, it's easy to remember with "Glossopharyngeal: Gag Reflex and Swallowing."
Vagus (CN X)
Vagus (CN X) - "Vagus Nerve: Wandering Nerve of the Body"
The vagus nerve (CN X) is a wanderer, affecting various parts of the body. Call it the "Wandering Nerve" using the mnemonic "Vagus Nerve: Wandering Nerve of the Body."
Accessory (CN XI)
Accessory (CN XI) - "Accessory Nerve: Shoulder Shrugging and Head Turning"
The accessory nerve (CN XI) governs actions like shoulder shrugging and head-turning. Remember it by associating it with "Accessory Nerve: Shoulder Shrugging and Head Turning."
Hypoglossal (CN XII)
Hypoglossal (CN XII) - "Hypoglossal Nerve: Stick Out Your Tongue"
Finally, the hypoglossal nerve (CN XII) manages tongue movement. Keep it in mind with the playful reminder "Hypoglossal Nerve: Stick Out Your Tongue."
How to remember the cranial nerve names
You should just use this rule:

- Ooh, ooh, ooh to touch and feel very good velvet. Such heaven!
Remembering functional information:
S: sensory; m: motor; b: both
- Some say marry money but my brother says big brains matter more
- Some say my mother bought my brother some bad beer, my, my
