Mnemonic for 12 cranial nerves and their types.

We know that there are 12 pairs of cranial nerves which originate from the brain and brainstem. Remembering the names of these cranial nerves is easily mastered but it is difficult to remember their type ie whether they are Sensory nerves, motor nerves or mixed nerves.

  1. Olfactory
  2. Optic
  3. Oculomotor
  4. Trochlear
  5. Trigeminal
  6. Abducens
  7. Facial
  8. Auditory/Vestibulocochlear
  9. Glossopharyngeal
  10. Vagus
  11. Spinal Accessory
  12. Hypoglossal

A simple mnemonic will help you to remember the types of cranial nerves.

  4. Trochlear- Money- Motor
  5. Trigeminal- But – Mixed
