Arteries of the Striatum Anterior

**Anterior striatal artery**

The arteries of the anterior portion of the striatum include the superficial anterior and middle arteries. The anterior artery is a direct continuation of the anterior cerebral artery, a lateral branch of the middle cerebral artery and is separated from it in the region of the lateral fissure of the hemisphere. The middle artery arises from the same anterior cerebral artery, connects with the superficial anterior artery, forming a common artery at the level of the posterior edge of the anterior section and is divided into anterior and posterior sections, penetrating into various parts of the forebrain and midbrain. Both arteries are better developed on the right. Each artery makes up the white crossbar of the anterior wall. The anterior and posterior sections converge almost in the middle of their length, the anterior artery is posterior, and the posterior artery is anterior. The basal surface of the anterior section is divided by the papillae of the anterior retinal trunk; from below it does not have a spongy structure; there are convex longitudinal sections lined with a thin layer of glial and somatic nerves. The posterior border of the white matter itself is directed slightly to the side and extends beyond the thalamus somewhat posteriorly. On each side of the thalamus there are central subcortical nuclei, cutaneous and individual dorsal nuclei. The striatum has a rounded shape. The inner surface is more convex in the upper part, less convex in the distal part. The thickness of the talum is 3-6 mm, the total length is over 25 mm. The anterior end of the thalamic striatum is located at the lower edge of the cerebral peduncle, where it contacts the outer gray matter on the lateral walls of the brain. Reaching the upper edge of the pons, the thalamic tract intersects perpendicular to the main axes of the brain and passes along the medial surface of the brainstem into the pons.
