Posterior central/perforating cerebral arteries

Arteriae centrales(alt.perforantes) posteriores

Cerebral arteries, posterior central artery group, Cerebral arteries, posterior perforant artery group

These narrow, initially unbranched, arteries are emitted as a bundle from the anterior part of the basal artery and from the first part of the posterior cerebrum artery . The vascular bundle penetrates the midbrain (mesencephalon) via the posterior vascular inlet (substantia perforata posterior) at the bottom of the cerebral arm pit (fossa interpeduncularis) and supplies the interior of the mesencephalon, the subthalamus area and the posterior parts of the thalamus.
