We often fail to remember them; here are the techniques to remember it:
- Foramen rotundum:
(R)otun(D)um = Ma(X)illary nerve
Mnemonic is “RDX”.
- Foramen OVALE:
Mnemonic is: “MALE”
M: Mandibular nerve
A: Accessory meningeal artery
L: Lesser petrosal nerve
E: Emissary vein.
- Foramen spinosum:
Middle meningeal vessels
Spino = Meningeal
Remember: “Spinal cord also has meninges”.
- Foramen (L)acerum:
Internal carotid artery (ICA)
Mnemonic is “LICA”.
- Jugular foramen:
CN – 9, 10, 11
But CN12 does not pass through jugular foramen (can come as an all except MCQ) as it passes through hypoglossal canal.
- Superior orbital fissure: CN 3, 4, V1, 6.
