posterior choroidal artery

The posterior choroidal artery is not in fact a single artery, although it is commonly referred to as such. The posterior choroidal arteries, often numbering up to 10 or 11 per hemisphere, are divided into medial posterior choroidal artery and lateral posterior choroidal artery groups. They usually arise from the P2 segment of the posterior cerebral artery and supply components of the brainstem.
