Posterior Perspective of the Arteries of the Brain of a Transparent Male

Description

Seen from a posterior perspective in a semi-transparent adult male head, the cerebral hemispheres are framed by the tentorial region and occipital skull outline while the posterior circulation is traced in red over the dorsal brainstem and cerebellar surface. Vertebral arteries ascend on either side of the medulla and unite at the pontomedullary junction to form the basilar artery, which runs superiorly along the ventral pons before bifurcating into the posterior cerebral arteries around the level of the midbrain. Paired posterior inferior cerebellar arteries, anterior inferior cerebellar arteries, and superior cerebellar arteries branch laterally from the vertebrobasilar system toward the cerebellum and posterior fossa structures. Clean symmetry. Posterior views like this are where the vertebrobasilar system makes clinical sense, because symptoms from posterior circulation ischemia map to brainstem, cerebellar, and occipital lobe territories rather than the classic anterior circulation aphasia and face arm weakness pattern. Basilar artery occlusion and distal vertebral artery stenosis can present with diplopia, dysarthria, vertigo, ataxia, or sudden coma, and the relationship of the basilar apex to the origins of the posterior cerebral and superior cerebellar arteries also aligns with common aneurysm sites at the basilar tip. For teaching the Circle of Willis, this angle keeps attention on the posterior communicating arteries as bridges between internal carotid inflow and posterior cerebral outflow, a point often lost in lateral or inferior renderings. Ideal placement includes neuroanatomy and cerebrovascular modules, stroke conference slide decks contrasting anterior and posterior circulation syndromes, and neurosurgical or endovascular education introducing vertebral artery access and basilar apex interventions. It also reads well in patient-facing materials when you need a clear explanation of vertebral and basilar artery flow without distracting facial features.
