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.
