Anatomy and function
The internal carotid arteries are important inputs to the anterior cerebral circulation. Their intracranial portions usually give rise to the ACA and MCA and connect to the posterior circulation through the posterior communicating arteries.
Where to look in the model
Only the intracranial terminal portions and nearby connections are illustrated.
What this view does not establish
The cervical course, carotid siphon and branches such as the ophthalmic artery are not fully drawn.
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.
