Long Fissures Seem To Store Only Nerves, Instead Of Arteries, Including Ophthalmic Veins
The order of the contents passing through the superior orbital fissure form superior to inferior:
- L: lacrimal nerve (branch of CN V1)
- F: frontal nerve (branch of CN V1)
- S: superior ophthalmic vein (tributary to cavernous sinus)
- T: trochlear nerve (CN IV)
- SO: superior division of the oculomotor nerve (CN III)
- N: nasociliary nerve (branch of CN V1)
- IO: inferior division of the oculomotor nerve (CN III)
- A: abducens nerve (CN VI)
- IOV: inferior ophthalmic vein (tributary to both cavernous sinus and pterygoid venous plexus)
Lazy French Tarts Sit Nakedly In Anticipation
The order of the nerves passing through the superior orbital fissure from superior to inferior:
- L: lacrimal nerve (branch of CN V1)
- F: frontal nerve (branch of CN V1)
- T: trochlear nerve (CN IV)
- S: superior division of the oculomotor nerve (CN III)
- N: nasociliary nerve (branch of CN V1)
- I: inferior division of the oculomotor nerve (CN III)
- A: abducens nerve (CN VI)
Live Frankly To See Absolutely No Insult
Note: not in order as abducens nerve is most inferior:
- L: lacrimal nerve (branch of CN V1)
- F: frontal nerve (branch of CN V1)
- T: trochlear nerve (CN IV)
- S: superior division of the oculomotor nerve (CN III)
- A: abducens nerve (CN VI)
- N: nasociliary nerve (branch of CN V1)
- I: inferior division of the oculomotor nerve (CN III)
Live Free To See No Insult At All
Note: not in order
- L: lacrimal nerve (branch of CN V1)
- F: frontal nerve (branch of CN V1)
- T: trochlear nerve (CN IV)
- S: superior division of the oculomotor nerve (CN III)
- N: nasociliary nerve (branch of CN V1)
- I: inferior division of the oculomotor nerve (CN III)
- At All: abducens nerve (CN VI)
