Morphology of the brain base arteries of the giant anteater (Myrmecophaga tridactyla)

This study aimed to describe the brain base arteries of Myrmecophaga tridactyla using ten cadavers adults from this species, including five male and female specimens. The arterial vascular bed was perfused via thoracic aorta with a dyed natural latex solution, animals were fixed preserved 10% formaldehyde buffered solution. encephala removed, their vessels dissected. Basilar artery formation occurred by anastomosis thick ventral spinal vertebral arteries. basilar formed two islands gave bulbar pontine branches, cranial, middle, caudal cerebellar ended forking into its terminal communicating blood supply encephalon derived solely vertebrobasilar system, circle closed caudally rostrally. absence participation internal carotid in irrigation, island formations artery, fusiform shape are peculiar characteristics anatomy M. tridactyla.
