Lateral lenticulostriate arteries

Dr Craig Hacking and A.Prof Frank Gaillard et al.

The lateral lenticulostriate arteries arise from the proximal middle cerebral artery (MCA) and supply the lateral portion of the putamen and external capsule as well as the upper internal capsule.

They are longer (almost twice the diameter) and more numerous than the medial lenticulostriate arteries, which arise more proximally along the M1 segment.

Some confusion may arise when discussing the lenticulostriate arteries origin, as some, including Osborne 1, divide them in those that arise from the M1 segment into medial (those arising proximally) and lateral (those arising more distally) groups. 

The lower anterior internal capsule, as well as the inferior head of caudate are supplied by the recurrent artery of Heubner, from the ACA
