Study Notes
Cranial Nerves
- There are 12 pairs of cranial nerves
- They originate directly from the brain, not the spinal cord
- They control various functions including senses, facial movements, and autonomic functions
- Each nerve has a name and a number (I to XII)
Key Functions
- Sensory (S): Carry sensory information (smell, sight, taste).
- Motor (M): Control muscles (eye movement, facial expression, tongue movement).
- Both (B): Some nerves are both sensory and motor (e.g., controlling a muscle while also sensing its stretch).
Mnemonic for Order
- "Oh, Oh, Oh, To Touch And Feel Very Green Vegetables, AH!"
- Olfactory (I) - Smell
- Optic (II) - Vision
- Oculomotor (III) - Eye movement, pupil reaction
- Trochlear (IV) - Eye movement
- Trigeminal (V) - Facial sensation, chewing
- Abducens (VI) - Eye movement
- Facial (VII) - Facial expression, taste, saliva/tears
- Vestibulocochlear (VIII) - Hearing, balance
- Glossopharyngeal (IX) - Taste (back of tongue), swallowing, saliva
- Vagus (X) - Heart rate, digestion, voice control
- Accessory (XI) - Shoulder movement, head turning
- Hypoglossal (XII) - Tongue movement
