Cranial Nerves Mnemonic:  Oh Oh Oh To Touch And Feel Very Good Velvet

The human body is an incredibly complex and intricate machine, and one of the most fascinating and essential systems in the body is the nervous system. The nervous system transmits messages and signals throughout the body, allowing us to move, feel, and experience the world around us. At the core of the nervous system are the 12 cranial nerves, which play a critical role in our sensory and motor functions. This blog post explores the 12 cranial nerves and their functions.

Oh, Oh, Oh, To Touch And Feel Very Good Velvet

  1. O-Olfactory
  2. O-Optic
  3. O-Oculomotor
  4. T-Trochlear
  5. T-Trigeminal
  6. A-Abducens
  7. F-Facial
  8. V-Vestibulocochlear
  9. G-Glossopharyngeal
  10. V-Vagus
  11. A-Accessory
  12. H-Hypoglossal


The cranial nerves are named according to their location or function. They are traditionally listed using the mnemonic “O-Olfactory, O-Optic, O-Oculomotor, T-Trochlear, T-Trigeminal, A-Abducens, F-Facial, V-Vestibulocochlear, G-Glossopharyngeal, V-Vagus, A-Accessory, H-Hypoglossal.”

The first two cranial nerves, Olfactory (I) and Optic (II) are responsible for our senses of smell and sight, respectively. 

The Oculomotor (III), Abducens (VI), and Trochlear (IV) nerves control the movements of our eyes and allow us to track objects, focus, and maintain equilibrium.

The Trigeminal (V) nerve is responsible for facial sensation and motor control, including chewing, while the Facial (VII) nerve controls the facial expression and taste sensation. The Vestibulocochlear (VIII) nerve is the sensory nerve of the internal ear and is responsible for hearing and balance.

The Glossopharyngeal (IX) and Vagus (X) nerves play critical roles in our autonomic nervous system by controlling heart rate and digestion. The Accessory (XI) nerve controls neck and shoulder movements, while the Hypoglossal (XII) nerve controls tongue movements and speech.

Injury or damage to any of the 12 cranial nerves can lead to a range of issues, from difficulty hearing or seeing to problems with speech, chewing, or even breathing and heart function.

Final Words

The 12 Cranial Nerve Mnemonic  are a vital part of our nervous system, allowing us to feel, move, and experience the world around us.

 From the sense of smell to tongue movements and heart rate, each nerve plays a unique and essential role in our bodily functions.

 By understanding these nerves and their functions, we can develop a deeper appreciation for the intricacies of the human body and the remarkable ways in which it functions.
