Anterolateral central arteries
The anterolateral central arteries (or antero-lateral ganglionic branches), a group of small arteries which arise at the commencement of the middle cerebral artery, are arranged in two sets:
- one, the internal striate, passes upward through the inner segments of the lentiform nucleus, and supplies it, the caudate nucleus, and the internal capsule;
- the other, the external striate, ascends through the outer segment of the lentiform nucleus, and supplies the caudate nucleus and the thalamus.
More modern texts divide the anterolateral central arteries into "lateral striate arteries" and "medial striate arteries".
