Lenticulostriate Arteries

The medial and lateral lenticulostriate arteries are smaller branches that come off from the first segment of the middle cerebral artery. Ranging in number between six and nine, they all have an ascending course and supply oxygenated blood to basal ganglia structures (part of head and body of caudate nucleus, globus pallidus, putamen), and the internal capsule.
