Lenticulostriate arteries
Updates to Article Attributes
The lenticulostriate arteries are a collection of small perforating arteries arising from the anterior part of the circle of Willis and supplying the basal ganglia.
They are divided into:
There is, however, some confusion as to this nomenclature. Most describe the medial arteries arising from the A1 segment of the anterior cerebral artery, and the lateral arteries arising from the M1 segment of the middle cerebral artery 2.
Some, including Osborne 1, divide the perforating arteries that arise from the M1 segment into medial (those arising proximally) and lateral (those arising more distally) groups.
Furthermore these perforating arteries can arise from other proximal branches (e.g. fronto-orbital artery) 3. It is therefore easier to consider these arteries from the point of view of the tissue they supply, rather than wherethe artery they arise formfrom.
