posterior , and lateral posterior choroidal arteries serve the plexuses of the lateral and third ventricles. The choroid plexus in the fourth ventri cle and the clump of choroid plexus protruding out of the foramen of Luschka are served by posterior inferior and anterior inferior cerebellar arteries , respectively. In B , the origins of these branches from their main arterial trunks are shown. See also Figures 2-24, 2-32, and 2-35.

4-14 Blood supply to the choroid plexus of the lateral, third, and fourth ventricles. Branches of the vertebrobasilar system and of the internal carotid artery and P 2 segment of the posterior cerebral artery that supply the choroid plexus are accentuated by appearing in a darker red shade. In A , a representation of these vessels (origin, course, termination) is shown from the lateral aspect. Anterior , medial
