Nerves in the superior orbital fissure

Level 2:

1. Lacrimal nerve (Vi)
2. Frontal nerve (Vi)
       Superior ophthalmic veins
3. Trochlear nerve (IV)
4. Superior division of oculomotor nerve (IIIs)
5. Nasociliary nerve (Vi)
6. Inferior division of oculomotor nerve (IIIi) + parasympathetic fibres
7. Abducens nerve (VI) + sympathetic fibres
       Inferior ophthalmic veins
"A blast from my past!  Does anyone recall the dirty mnemonic that helps you remember the structures that pass through the superior orbital fissure? If you do please share with us."

"I will post a case study in the next few days that will illustrate why you should try and remember the anatomy of this structure."

  1. Lazy French Tarts Sit Nakedly In Anticipation

    Lazy French Tarts Sit Nakedly In Anticipation is an acronymn that describes the order of the nerves passing through the superior orbital fissure:

    Lazy = lacrimal nerve
    French = frontal nerve (a branch of the ophthalmic nerve)
    Tarts = trochlear nerve (CN IV)
    Sit = superior division of the oculomotor nerve (CN III)
    Nakedly = nasociliary nerve (a branch of the ophthalmic nerve)
    In = inferior division of the oculomotor nerve (CN III)
    Anticipation = abducens nerve (CN VI)
