Exploration of the brain from its basal aspect
Arteries of basal surface of brain
The vertebral and internal carotid arteries are visible as they reach the basal surface of the brain to enter into the formation of the arterial circle of Willis. A portion of the right temporal lobe has been cut away to reveal the middle cerebral artery with some of its branches deep in the lateral fissure. The optic chiasm is partially removed to display the anterior communicating artery. The internal auditory arteries are not clearly demonstrated in this specimen.
