ABSTRACT
Thirty ostrich (Struthio camelus) brains were used, injected with latex, to describe the arteries of the brain base.The largest occurrences of the arteries were The cerebral carotid artery (100%), the intercarotid anastomosis(100%). The caudal branch of the cerebral carotid artery was, on the right (R), developed (53.3%) and vestigial(46.7%); on the left (L), developed (66.7%) and vestigial (33.3%). The ventral tectal mesencephalic artery onthe R (53.3%), on the L (66.7%), direct branch of the cerebral carotid artery on the R (43.3%), on the L (30%)and, direct branch of the basilar artery (3.3%) in both antimeres. The basilar artery was a single vessel (80%),double in (13.3%) and âin islandâ formation (6.7%). The caudal ventral cerebellar artery was single (96.7%),double (3.3%) on the R and, single (93.3%), double (6.7%) on the L. The dorsal spinal artery was a collateralbranch of the caudal ventral cerebellar artery on the R (96.7%), on the L (93.3%). The ventral spinal artery wasdouble (90%) and single (10%). The rostral branch of the cerebral carotid artery (100%). The caudal cerebralartery, on the R, was double (90%) and single (10%); on the L, was double (53.3%) and single (46.7%). Themiddle cerebral artery was a single vessel (100%). The cerebroethmoidal artery was single (100%). The rostralcerebral artery was single (90%), double (10%) on the R and single (96.7%), double (3.3%) on the L. Thecerebral arterial circle was rostrally open (100%) and, caudally, open (80%) and closed (20%).
