Anatomy and function
The posterior cerebral artery usually arises at the end of the basilar artery. It courses around the midbrain and mainly supplies the occipital lobe and parts of the medial and inferior temporal lobe.
Where to look in the model
The proximal segment connects with the posterior communicating artery. Major posteriorly directed branches are illustrated.
What this view does not establish
Common variants, including the fetal-type configuration, are not shown. A highlighted artery does not define an exact tissue-supply territory.
Open in 3DSources and precision
Cortex uses the FreeSurfer fsaverage5 template surface, with 10,242 vertices per hemisphere. Functional references use selected Destrieux sulcal and gyral parcels. Deep structures use fsaverage aseg segmentations. The Sereno2020 cerebellar research surface preserves folial geometry, but comes from another specimen; its assembled placement is schematic, without medical registration across templates. Arterial paths are manually drawn teaching schematics, not CTA/MRA reconstructions.
An educational schematic prototype for understanding spatial relationships. Item-by-item independent neuroanatomical review is pending. Functional highlights are not results of an individual examination and do not support individual diagnosis or treatment decisions.
