A useful mnemonic to remember the branches of the internal carotid artery is:
- A VIP'S COMMA
- A: anterior choroidal artery (C7)
- V: Vidian artery (C2)
- I: inferolateral trunk (C4)
- P: posterior communicating artery (C7)
- S: superior hypophyseal artery (C6)
- C: caroticotympanic artery (C2)
- O: ophthalmic artery (C6)
- M: meningohypophyseal trunk (C4)
- M: middle cerebral artery (C7)
- A: anterior cerebral artery (C7)
The last two branches in the mnemonic are the terminal branches of the internal carotid artery.
Except for the terminal segment (C7) the odd numbered segments usually have no branches, whereas the even numbered segments (C2, C4, C6) each have two branches.
