Human brain - central arteries - anterior-midsagittal view

1. Hypothalamus
2. Thalamus
3. Mesencephalon
4. Pons
5. Medulla oblongata

The small “Central Arteries” which take origin from the Arterial Circle are arranged in four groups:

• Anteromedial – from the anterior cerebral and anterior communicating arteries.
• Posteromedial – (also called thalamoperforating) from the posterior communicating and medial portion of the posterior cerebral arteries.
• Posterolateral – (also called thalamogeniculate) from the lateral portion of the posterior cerebral arteries.
• Anterolateral – (also called lateral striate or lenticulostriate) arising from the middle cerebral artery.
