Lecture Notes: Cranial Nerves Mnemonics and Tricks

Introduction

• Focus on mnemonics and tricks to remember cranial nerve names and functions.
• Emphasis on remembering cranial nerves with the same starting letter.
• Notes and study guides available.

Cranial Nerve Names

• There are 12 pairs of cranial nerves:
  1. Olfactory
  2. Optic
  3. Oculomotor
  4. Trochlear
  5. Trigeminal
  6. Abducens
  7. Facial
  8. Vestibulocochlear
  9. Glossopharyngeal
  10. Vagus
  11. Accessory
  12. Hypoglossal

Mnemonic for Cranial Nerve Names

• Mnemonic: "Only One Of The Two Athletes Felt Very Good, Victorious, And Healthy."
  • Helps remember the order and names of cranial nerves.
  • Encouraged to choose a mnemonic that works best individually.

Cranial Nerve Functions

• Cranial nerves can be sensory, motor, or both:
  • Sensory: Sends sensory information to the brain.
  • Motor: Sends information from the brain for movement.
  • Both: Mix of sensory and motor.

Mnemonic for Cranial Nerve Functions

• Mnemonic: "Some Say Merry Money But My Brother Says Big Brains Matter Most."
  • Sensory = S, Motor = M, Both = B.
  • Cranial Nerve Functions:
    1. Sensory
    2. Sensory
    3. Motor
    4. Motor
    5. Both
    6. Motor
    7. Both
    8. Sensory
    9. Both
    10. Both
    11. Motor
    12. Motor

Tricks for Cranial Nerves with the Same Starting Letter

• O – Olfactory, Optic, Oculomotor:

  • Olfactory (Cranial Nerve 1) - Smell, "One Nose."
  • Optic (Cranial Nerve 2) - Vision, "Two Eyes."
  • Oculomotor (Cranial Nerve 3) - Motor, contains "motor."

• T – Trochlear, Trigeminal:

  • Trochlear (Cranial Nerve 4) - Use "o" in Trochlear and 4.
  • Trigeminal (Cranial Nerve 5) - Use "i" in Trigeminal and 5.

• A – Abducens, Accessory:

  • Abducens (Cranial Nerve 6) - "Abdu-6."
  • Accessory (Cranial Nerve 11) - Pairs of letters and "11."

• V – Vestibulocochlear, Vagus:

  • Vestibulocochlear (Cranial Nerve 8) - "Ear and Equilibrium (E)" for 8.
  • Vagus (Cranial Nerve 10) - "Thorax and Tummy (T)" for 10.
