A = medulla; B = pons; C = midbrain; D = cerebellum. Main arterial trunks: 1 = vertebral artery; 2 = anterior spinal artery; 3 = posterior inferior cerebellar artery; 4 = basilar artery; 5 = anterior inferior cerebellar artery; 6 = superior cerebellar artery; 7 = posterior cerebral artery; 8 = collicular artery; 9 = posteromedial choroidal artery; 10 = anterior choroidal artery. Arteries of the anterior and lateral aspects of the brainstem: 11 = anteromedial group of medullary arteries; 12 = anterolateral group of medullary arteries; 13 = lateral group of medullar arteries (arteries of the lateral medullary fossa), 14 = anteromedial group of pontine arteries, penetrating the basilar sulcus (14), penetrating the interpeduncular fossa (14 prime) (inferior rami of the interpeduncular fossa), penetrating the foramen cecum (14 double prime); 15 = anterolateral group of pontine arteries; 16 = lateral group of pontine arteries originating from the superior lateral pontine (16 prime) and the inferior lateral pontine (16 double prime) arteries and from the anterior inferior cerebellar artery; 17 = anteromedial group of mesencephalic arteries (middle rami of the interpeduncular fossa); 18 = thalamoperforating arteries (superior rami of the interpeduncular fossa); 19 = anterolateral group of midbrain arteries. Arteries of the anterior aspect of the cerebellum: 20 = branches of the superior cerebellar artery; 21 = branches of the anterior inferior cerebellar artery; 22 = branches of the posterior inferior cerebellar artery. Posterior view of medulla and pons after removal of the cerebellum by sections of the cerebellar peduncle. A = posterior aspect of the lower medulla; A prime = posterior aspect of the upper medulla; B = posterior aspect of the pons (superior cerebella
