Anterolateral central arteries

The anterolateral central arteries (antero-lateral ganglionic branches or lenticulostriate arteries) are a group of small arteries arising from the anterior part of the circle of Willis and supply the basal ganglia. They arise at the commencement of the middle cerebral artery and are arranged in two sets: 1. * Internal striate: passes upward through the inner segments of the lentiform nucleus and supplies the lentiform nucleus, caudate nucleus, and internal capsule; 2. * External striate: ascends through the outer segment of the lentiform nucleus and supplies the caudate nucleus.
