Anterior cerebral artery — schematic anatomical location
An actual rendered view of the interactive model, with the selected structure labelled. Use it as a schematic location reference and read the precision notes alongside it.

Anatomy and function

The anterior cerebral artery usually arises from the internal carotid artery, enters the longitudinal fissure medially and courses near the corpus callosum. It mainly supplies medial parts of the frontal and parietal lobes.

Where to look in the model

The proximal left and right anterior cerebral arteries are connected by the anterior communicating artery.

What this view does not establish

Only major connections and selected surface branches are illustrated. Branching and supply territories vary; exact territorial boundaries are not shown.

Sources 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.
