Lenticulostriate Arteries

Branch of M1 Segment of MCA.

Supplies basal ganglia structures: Part of head and body of caudate, globus pallidus, putamen, and the posterior limb of the internal capsule.

Lateral Lenticulostriate A.:

Damage to the internal capsule resulting in contralateral hemiparesis and sensory deficit. Speech may be affected (medial temporal lobe) as well as visual function (Meyer's loop: optic radiations affected).
