Study Notes
Cranial Nerves
- There are 12 pairs of cranial nerves that originate from the brain or brain stem.
- Cranial nerves are numbered based on where they emerge from the brain, from front to back.
Mnemonics
- Oh Oh Oh To Touch And Feel Very Good Velvet Ah Heaven can be used to remember the 12 cranial nerves.
- Some Says Money Matters But My Brother Says Big Boobs Matter Most can be used to remember the 3 functions of cranial nerves (Sensory, Motor, Both).
Cranial Nerve I: Olfactory Nerve
- Function: Carries impulses for the sense of smell.
- Origin: Fibers arise from olfactory receptors in the nasal mucosa and synapse with the olfactory bulbs, which send fibers to the olfactory cortex.
Cranial Nerve II: Optic Nerve
- Function: Carries impulses for vision.
- Origin: Fibers arise from the retina of the eye and form the optic nerve.
