🏛️ Visual
Memory Palace Technique
VISUAL ASSOCIATION METHOD
Place Each Nerve in a Familiar Location
Walk through a familiar place in your mind and associate each nerve with a vivid image. Olfactory (I) = old person smelling flowers at the front door. Optic (II) = giant camera lens in the hallway.
🔗 Association
Pegword Method
RHYME & OBJECT ASSOCIATIONS
Link Each Nerve to a Rhyming Word or Object
Associate each nerve with a rhyming or visually memorable object. Olfactory = Oldman with a big nose. Facial = Face mask. Vagus = Vague, wandering traveler.

The Wanderer
VAGUS NERVE — CN X
Remember What the Vagus Nerve Does
Vagus means "wandering" in Latin — it wanders from the brainstem all the way to the abdomen controlling heart rate, breathing, and digestion. The longest and most influential cranial nerve.
🔺 Branches
Standing Room Only
TRIGEMINAL BRANCHES — V1, V2, V3
Remember the 3 Branches of CN V
The Trigeminal has 3 branches — Ophthalmic (V1), Maxillary (V2), Mandibular (V3). Think: top of face, middle of face, bottom of face — like three floors of a building from top to bottom.

EYE MOVEMENT NERVES
Which Nerves Control Eye Movements
Lateral Rectus = CN VI (Abducens). Superior Oblique = CN IV (Trochlear). All other eye muscles = CN III (Oculomotor). Eye cannot move laterally — think CN VI. Drooping eyelid — think CN III.
