Blood supply of internal capsule comes from 3 main arteries, they are
1) Lateral striate branches of middle cerebral artery.
2) Medial striate branches of anterior cerebral artery.
3) Anterior choroidal branches of internal carotid artery.
Lateral striate branches of middle cerebral artery supply
Anterior limb
Genu
Posterior limb
Basal ganglia
Medial striate branches of anterior cerebral artery supply
Anterior limb
Genu
Basal ganglia
Anterior choroidal branches of internal carotid supply
Posterior limb
Retrolenticular part
Anterior limb is supplied by the following arteries
Anterior cerebral artery through medial striate branch.
Middle cerebral artery through lateralstriate and lenticulostriate branches.
Genu is supplied by
Anterior cerebral artery through medial striate branch.
Middle cerebral artery through lateral striate and lenticulostriate branch.
Branches of internal carotid artery.
Posterior limb is supplied by
Middle cerebral artery through lateral striate and lenticulostriate branch. It is called Charcot’s artery of cerebral haemorrhage.
Anterior choroidal artery, a direct branch of internal carotid artery As it is long and slender it has tendency to get thrombosis.
