How to Remember Cranial Nerves?

Medical, nursing and paramedical students have to do so much of the study-related works in little time. They don’t even get enough time to review for quarterly and board exams. They are forced to memorize a whole lot of information in no time. In such hard times come medical acronyms and medical mnemonics to relieve the pain of medical students. Cranial nerves acronym or mnemonic for cranial nerves helps students to remember the 12 cranial nerves and their functions for long-term memory.

We will provide you with a short introduction to cranial nerves and their functions, along with the tricks or acronyms for cranial nerves and mnemonic for cranial nerve functions.

What are cranial nerves?

Cranial nerves are the 12 paired nerves that connect the brain to different parts of the head, neck, throat, and visceral organs. The 12 cranial nerves are named for their structure or function. Each nerve is represented by a corresponding Roman numeral from I to XII.

How many cranial nerves are there?

As we mentioned above, there are twelve cranial nerves. The majority of the cranial nerves (III – XII) emerge from the brain stem, whereas the olfactory and optic nerves arise from the cerebrum. The trochlear nerve (IV) arises from the posterior side of the midbrain. The oculomotor nerve comes from the midbrain-pontine junction. Similarly, the trigeminal nerve (V) has its origin at the Pons and the pontine-medulla junction gives rise to abducens, facial, and vestibulocochlear (VI-VIII) nerves. The medulla oblongata is the origin of the glossopharyngeal, vagus, accessory (IX) nerves. They arise from the region posterior to the olive. Likewise, the area anterior to the olive of the medulla oblongata gives rise to the hypoglossal (XII) nerve.

The 12 cranial nerves are listed below:

Cranial Nerve I or CN I: Olfactory Nerve

Cranial Nerve II or CN II: Optic Nerve

Cranial Nerve III or CN III: Oculomotor Nerve

Cranial Nerve IV or CN IV: Trochlear Nerve

Cranial Nerve V or CN V: Trigeminal Nerve

Cranial Nerve VI or CN VI: Abducens Nerve

Cranial Nerve VII or CN VII: Facial Nerve

Cranial Nerve VIII or CN VIII: Vestibulocochlear Nerve

Cranial Nerve IX or CN IX: Glossopharyngeal Nerve

Cranial Nerve X or CN X: Vagus Nerve

Cranial Nerve XI or CN XI: Accessory Nerve

Cranial Nerve XII or CN XII: Hypoglossal Nerve
