Definition
The anterolateral central arteries (antero-lateral ganglionic branches or lenticulostriate arteries) are a group of small arteries which arise at the M1 segment of the middle cerebral artery. They enter the brain via central and lateral parts of the anterior perforating substance and supply the substantia innominata, putamen, globus pallidus, head and body of the caudate nucleus, internal capsule and adjacent corona radiata, and the central portion of the anterior commissure.
They are arranged in two sets:
- Proximal lateral striate branches that pass through the lentiform nucleus to the caudate nucleus
- Distal lateral striate branches that pass laterally around the lentiform nucleus to the caudate nucleus
